Bras are one of the most complex pieces of apparel. There are lots of different styles, and each style has a dozen different sizes, and within that there are a lot of colors. Furthermore, there is a lot of product engineering. You've got hooks, you've got straps, there are usually two parts to every cup, and each requires a heavy amount of sewing. It is very component intensive. [48] Asymmetric breasts [ edit ] The breasts should be enclosed by the cups and there should be a smooth line where the fabric at the top of the cup ends.

Ensure that the tape is parallel to the ground and snug but not too tight. It should sit firmly against your skin. For women with smaller cup sizes like AA, AAA, or A, they may have more freedom in choosing bra styles and can opt for bralettes, unlined bras, and bras without underwire. B cup breasts typically require little support, while C cups can vary in their need for support. D cups and above require prioritizing support and choosing bras with additional features such as wide, padded straps, sectioned cups, and underwire for optimal comfort and breast health.Experts suggest that women choose a bra band that fits well on the outermost hooks. [43] [44] This allows the wearer to use the tighter hooks on the bra strap as it stretches during its lifetime of about eight months. [44] The band should be tight enough to support the bust, but the straps should not provide the primary support. [46] Consumer measurement difficulties [ edit ]

Each cup's underwire at the front should lie flat against the sternum (not the breast), along the inframammary fold, and should not dig into the chest or the breasts, rub or poke out at the front. If a cup is a hemisphere, its volume V is given by the following formula: [101] V = 2 π r 3 3 = π D 3 12 {\displaystyle V={\frac {2\pi r A difference of seven inches between your bust and band measurement defines a G cup size. If you wear a G cup size, you will almost certainly need to buy your bras from a specialty bra retailer. While this can take some extra effort, it is more than worth it if it helps you find bras that fit you. Double letter GG cup size also exists to fit women whose bust measures between seven and eight inches more than their band measurement. Dutch model Lara Stone’s cup size is estimated to fall within this transitional range that defines a GG cup.When shopping for bra sizes as large as HH, don’t get discouraged. Keep exploring different brands and styles until you find a well-fitting bra that is sexy and provides you with all the support you need to eliminate the dangers of chronic pain and other discomforts. Conclusion This system has been standardized in the European dress size standard EN 13402 introduced in 2006, but was in use in many European countries before that date. Bra sizing in the United States is very similar to the United Kingdom. Band sizes use the same designation in inches and the cups also increase by 1-inch-steps. However, some manufacturers use conflicting sizing methods. Some label bras beyond a C cup as D-DD-DDD-DDDD-E-EE-EEE-EEEE-F..., some use the variation: D1, D2, D3, D4, D5..... but many use the following system: A, B, C, D, DD, DDD, G, H, I, J, K, L, M, N, O. and others label them like the British system D-DD-E-F-FF... Comparing the larger cup sizes between different manufacturers can be difficult. [ citation needed] Now that you have your band size and cup size measurements, you can calculate your bra size.
