Know that cup size is not absolute. This is the biggest myth about bra sizes: that a D loving cup looks the same on every band size, or that having pocket-size breasts automatically means you're an A cup. Actually, cup size is proportional to band size — meaning it's dependent on your ring measurement. For instance, a 32 D will fill out less volume than a 36 D, just they're both D cups. The cup size (the letter) is determined past the divergence between your underbust and bust measurements. A 32D would mean you have a 32 inch underbust and a 36 inch bust, whereas a 32A would hateful you accept a 32 inch underbust and a 33 inch bust. ^[1]

Sympathise how a correctly fitted bra should look and feel. There are a few tell-tale signs that indicate whether or not a bra fits you. Here'due south what to proceed an eye out for as you're measuring yourself and trying on unlike sizes:^[2]
- A snug band: The band is what should practice the bulk of the piece of work supporting your breasts, non the straps. Y'all should be able to put one or two fingers under the band, but no more. Straps falling off your shoulders or your band riding up are signs yous need a smaller band; straps digging into your shoulders tin be a sign it is too small-scale.
- Sufficient side coverage: You shouldn't have whatsoever tissue coming out from the sides of the cups, beneath your armpits. On an underwire bra, you can appraise side coverage with the underwire: if the stop of it is pointing toward the center of your armpit, yous're good to go.
- A flat gore: The gore (the part of the bra ring that's between the cups) should sit flat confronting your breast, without digging into your pare uncomfortably. If information technology doesn't, yous're wearing the wrong bra.
- A smooth curve: Avert the dreaded "quad-puppet" that results from the top of a also-small cup cutting into breast tissue to a higher place the bra. Instead, look for a fit that results in a make clean silhouette with no devious tissue.
3
Be aware of dissimilar chest shapes. And then what happens if you find a bra in your size, merely it still fits wrong? You're probably not picking the right bra cut for your breast shape. Endeavor these solutions to common shape issues:^[3]
- Shallow breasts: If your chest tissue is evenly spread over a wider area, with less project, you probably have a shallow shape. (Some other tell-tale sign: having breast tissue near your collarbones despite being relatively pocket-size-disrepair.) Shallow breasts fit best in balconette or demi-cup bras, with a cup that's open on top and cut horizontally. Avoid plunge styles.
- Pendulous or tuberous breasts: If the base of your breast is relatively narrow, merely the actual tissue hangs down quite a scrap, don't despair! Instead, wait for bras that have underwires, well-separated cups and fuller chest coverage. Avoid demi cups and plunge bras.
four
Know nigh sister sizes. If you find a bra that'south close to a perfect fit just non quite there, attempt a sister size. It might provide just enough variation to correct the slight differences between manufacturers.^[4]
- Go down a sister size: Reduce your band size by two, simply take your cup size upwards one interval. For example, you might go from a 36 C to a 34 D.
- Get upward a sister size: Increment your band size by 2, but go downwards 1 loving cup size. For instance, you might go from a 36 C to a 38 B.
- Once y'all detect your true bra size, some women may even so chose a sis size in certain scenarios, such as with a difficult to find bra size. If y'all chose to do this, know that going up or downward by more one size ordinarily results in a band that is much likewise large or likewise small.
5
Navigate dissimilar plumbing fixtures styles. Currently, there are 2 different bra fitting styles (outlined beneath). The modern measurement is beingness adopted by more manufacturers, though some however use the traditional style. Unfortunately, information technology's difficult to know which system private designers and labels utilise. Hither's how to hedge your bets:^[five]
- If you're trying on bras in a store, it's a practiced idea to know what your size is for both styles.
- If you're ordering online, try to notice a site that has a flexible return policy.
vi
Be wary of professional fittings. Asking for a seasoned professional to measure y'all is a corking idea if you lot're starting from square i — she'll probably be able to advise cuts and styles that could work for you. However, being fitted comes with a few caveats:
- Avert stores that carry a express range. A fitter at i of these shops might try to incorrectly sell y'all a size that they have on-hand, instead of your truthful size. Earlier yous commit to a fitting, make certain the store carries smaller band sizes (such as 28 and 30) and larger cups (DDD and up). Expert choices in the US include section stores similar Nordstrom and Dillard's.
- Enquire to exist fitted with both measurement systems. That manner, you have an idea of what size to try if one manner produces a completely incorrect fit.
- Don't go out your current bra on. If your fitter tries to measure yous with your bra notwithstanding on, it's probably not going to be the correct measurement. If you're concerned about modesty, wear a sparse but close-fitting tank acme to your plumbing equipment, and simply remove the bra underneath.

1
Measure your ring size. This is the easiest part of the process — your ring size should be fairly stable and straightforward.^[6]
- Run a record mensurate all the style effectually your body just underneath your breasts and take a measurement in inches.^[7] Make sure the tape measure is horizontal and adequately snug. Your arms should be down. Write down this number.
- If this measurement is an odd number, then you should try out bras in both the size below your measurement and the size above. ^[8] For instance, if you lot measured 31 inches (78.7cm), your ring size could exist 30 or 32.
- If your measurement is already an even number, this is most always your band size, simply yous may demand a smaller or larger size depending on your body type. For example, if your ring size is smaller than 28, you may want to go upwards a band size since these sizes run quite tight. If yous do this, you lot should go down a cup size so your cups volition accept the aforementioned volume (known equally a 'sister size'). And so if you lot are a 26C, you may find a 28B is more comfortable.
two
Determine your cup size. Remember, your cup size isn't an accented measure — it'due south in proportion to your band size.^[9]
- Bend over so that your chest is parallel to the ground. This is and then that y'all'll be measuring all of your breast tissue — not just what protrudes outward when you're standing up.
- Measure out around your torso, so that the tape is over the fullest office of your breasts.^[x] Don't pull the tape too tightly — it should exist tight enough that it doesn't evenly move, but non and then tight that'due south pressing into your breast tissue. Write downwards the number.
- Make certain your tape measure is level to the ground. It shouldn't be a few inches down your back, or you'll end upwardly with an uneven measurement. To combat this, endeavor to measure yourself in front of a mirror, or ask your partner or close friend to help you.
- Calculate your cup size. To do this, y'all'll subtract your ring measurement from the cup measurement you lot just took. The deviation between the two numbers determines your cup size:
  - Less than ane inch (2.5 cm) = AA
  - ane inch (two.five cm) = A
  - 2 inches (5 cm) = B
  - 3 inches (seven.five cm) = C
  - 4 inches (ten cm) = D
  - five inches (12.5 cm) = DD
  - 6 inches (xv cm) = DDD (East in United kingdom of great britain and northern ireland sizing)
  - seven inches (18 cm) = DDDD/F (F in UK sizing)
  - 8 inches (20.v cm) = G/H (FF in UK sizing)
  - 9 inches (23 cm) = I/J (G in United kingdom sizing)
  - 10 inches (25.five cm) = J (GG in Britain sizing)
  - The majority of leading brands utilise UK loving cup sizing: AA, A, B, C, D, DD, E, F, FF, K, GG, H, HH, J, JJ, K, KK, L, LL. If y'all're shopping in the The states you lot might see cup sizes such as DDD or DDDD. These are equivalent to E and F. If y'all're in whatever doubt, particularly with larger cup sizes, you lot tin can refer to an international bra sizing nautical chart.

Try on a bra with the band and cup size you lot've arrived at in these steps. You should not regard this as your definitive size until you have tried on a few bras, and even and then you will often find you need a different size in dissimilar brands or styles of bra.
2
Put on the bra on correctly. Known as the "scoop and swoop," this is a more right way to make sure all of your chest tissue is in the bra:^[11]
- Afterwards taking the bra off its hanger the shoulder straps volition need to be lengthened. Put your arms through them and lean forward slightly so that your bust falls into the cups.
- Fasten the bra on the largest ready of hooks and optics. Don't worry if it'south tricky to fasten, if you're trying a smaller back size you lot volition notice that you need to stretch it effectually you to brand the hooks and optics meet.
- Still leaning forward, take concord of the underwires and give them a wiggle from side to side to make certain you lot're settled comfortably into the cups.
- For each side in plow, skid your hand into the side of the cup and lift each breast towards the centre.
- You will probably have to adjust the length of the shoulder straps. Skid them off your shoulders and suit the sliders so that the straps are short enough to stay in identify but don't cut in.
3
Cheque the band size. The right band size is the smallest yous can comfortably article of clothing. (This might be smaller than your underbust measurement-bra bands are quite stretchy, peculiarly at 42+.) Information technology needs to be firm enough that the bra is still fairly supportive without weighing down heavily on the shoulder straps.^[12]
- You should be able to run your fingers around the inside of the band, just not much more. A good rule of pollex is that you lot should be able to fit no more than than a fist under the back of the bra where your spine is at.
- It should fit on the biggest adjustment, but will probably exist as well tight if yous endeavor to fasten it on the smallest size. Bras are designed to fit similar this so that you tin tighten the band as the elastic starts to wear out.
- If the band is roomy plenty for you to be able to comfortably fasten it on the tightest adjustment, endeavour a smaller band, for example if a 32D is likewise loose, try a 30DD. Remember that the loving cup size has to exist changed when y'all move to a different ring size - for every ring you get downwards, you must go up by i loving cup size in lodge for the cups to remain the same capacity and vice versa.
- If you find the band painfully tight you should endeavor going up a cup size because too modest of cups can make a band which is too big or the right size seem ill plumbing fixtures. If going up a size, perhaps fifty-fifty several does not work, so endeavor going a band up and a cup down, east.g. 28G to 30FF. Even so, try the first method before the latter.
iv
Bank check the cup size. The right cup size should exist completely filled out with no wrinkling of the fabric or infinite in the cups, merely whatsoever spillage or "double boob" means the loving cup size is too pocket-sized, even in low cut or pushup bras.^[13]
- Check around the cups for whatever bulging, non only at the front but also at the sides under your artillery.
- Make certain the underwire encloses your whole breast and lies apartment against your rib muzzle.
- Bank check at the sides under your artillery to make sure the underwires are sitting on your ribs, non on soft breast tissue. If they're cutting into the sides of your breasts then yous need a larger cup size. Also be enlightened that if you have been wearing a bra with a too big band and too small cups, you may have concluded up with migrated tissue, which will seem to exist armpit rolls, or back rolls. This can be stock-still later on getting a well fitting bra.
- If the underwires are pressing painfully against your breastbone at the middle front y'all may need a smaller loving cup size or you could try a plunge style with a lower eye front (this is more likely to be an issue with the cups than the ring.) Or you might merely be human, and it's the shaping of your ribcage. In that case, wait for the bra to be "broken in" and meet how it fits and so, or get with the lower center front.
- If you think the cups might be as well small but yous're non sure, try on a bigger cup size as well to double cheque. It will usually be obvious if the smaller size fits better.

See how it looks with your superlative on. Yous've found a new bra that fits well, mayhap in a different size or style to the ones you're used to. Now information technology's time to see what it does for your figure! If you lot're trying a t-shirt bra it'south also important to make sure it gives you lot a smooth line nether fitted clothes.
- If you look side on to the mirror, you should exist able to come across that your bust is approximately halfway between your elbow and your shoulder.
- In a well fitting bra, your bustline volition be supported at the right level. A lot of people find that their apparel fit a lot better, and they discover a waist that could never be seen before! If your bustline had previously been quite depression because of a poorly supporting bra, you may even detect that you need to wear a smaller dress size.
- A fitted t-shirt will show upward any bulges from cups which are likewise small-scale, and too a moulded bra that is not filled out will testify lines at the bust where the edge of the cups are visible. It'southward also useful to make sure that the colour of your bra is non showing through a thin or light coloured top - if you need to brand your bra invisible, become for seamless cups which match your ain peel colour rather than the colour of your tiptop.
- It is a mutual business organization that wearing a smaller band size will brand a big bulge around your back. Still, these bulges are actually caused by the back of the bra riding up when information technology is too large. You should find that when the band sits lower at the back, it fits firmly and remains horizontal, rather than pushing upwardly creating a bulge.

1
Mensurate your band size. Wrap a tape measure effectually your ribcage, just beneath where your breast tissue ends. And so:^[14]
- If the measurement is even: Add 4 inches (10 centimeters).
- If the measurement is odd: Add five inches (12.5 centimeters).
- Be aware that most brands no longer use this ring measurement system. The "add four" method was popularized past Warners in the 1930s when bra blueprint was in its infancy and it simply doesn't piece of work with modernistic bras.^[15] Still, it'due south good to be enlightened that information technology'south out there.
ii
Measure your cup size. Stay standing up, and wrap the tape measure out around the fullest part of your breasts. (Keep the tape as horizontal as possible — make certain that information technology'due south not sagging around your back.) Subtract your band size from this new number to calculate your cup size:^[16]
- Less than 1 inch = AA
- i inch (ii.5 cm) = A
- 2 inches (v cm) = B
- iii inches (7.5 cm) = C
- 4 inches (10 cm) = D
- v inches (12.5 cm) = DD
- 6 inches (15 cm) = DDD (E in UK sizing)
- 7 inches (xviii cm) = DDDD/F (F in United kingdom of great britain and northern ireland sizing)
- 8 inches (twenty.5) = Chiliad/H (FF in UK sizing)
