Constructing a properly fitting brassiere is difficult. Adelle Kirk, formerly a manager at the global Kurt Salmon management consulting firm that specializes in the apparel and retail businesses, said that making bras is complex: In South Korea and Japan the torso is measured in centimetres and rounded to the nearest multiple of 5cm. Band sizes run 65-70-75-80..., increasing in steps of 5cm, similar to the English double inch. A person with a loosely measured underbust circumference of 78–82cm should wear a band size 80.

Researchers ruled out increases in population weight as the explanation and suggested it was instead likely due to more women wearing the correct, larger size.

Here are some recommended articles: 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 rThe UK and US use the inch system. The difference in chest circumference between the cup sizes is always one inch, or 2.54cm. The difference between 2 band sizes is 2inches or 5.08cm. Surveys of bra sizes tend to be very dependent on the population studied and how it was obtained. For instance, one U.S. study reported that the most common size was 34B, followed by 34C, that 63% were size 34 and 39% cup size B. However, the survey sample was drawn from 103 Caucasian student volunteers at a Midwest U.S. university aged 18–25, and excluded pregnant and nursing women. [71] Triumph Survey Country Your cup size refers to the letter part of your bra size (e.g., A, B, C, D, etc.). To measure your cup size: This system has been standardized in the Korea dress size standard KS K9404 introduced in 1999 and in Japan dress size standard JIS L4006 introduced in 1998.

Manufacturers' marketing and advertising often appeals to fashion and image over fit, comfort, and function. [30] [91] Since about 1994, manufacturers have re-focused their advertising, moving from advertising functional brassieres that emphasize support and foundation, to selling lingerie that emphasize fashion while sacrificing basic fit and function, like linings under scratchy lace. [92] Engineered Alternative to traditional bras [ edit ] The band measurement system was created by U.S. bra manufacturers just after World War II. [ citation needed] Other innovations [ edit ]Now that you have your band size and cup size measurements, you can calculate your bra size. Follow these steps: Cup sizes vary from one country to another. For example, a U.S. H-cup does not have the same size as an Australian, even though both are based on measurements in inches. The larger the cup size, the bigger the variation. [68] Over the bust/band measurement difference and cup size [69] [70] Difference

The French and Spanish system is a permutation of the Continental European sizing system. While cup sizes are the same, band sizes are exactly 15cm larger than the European band size. Multiple hook and eye closures were introduced in the 1930s that enabled adjustment of bands. Prior to the widespread use of bras, the undergarment of choice for Western women was a corset. To help women meet the perceived ideal female body shape, corset and girdle manufacturers used a calculation called hip spring, the difference between waist and hip measurement (usually 10–12 inches (25–30cm)). [12] Currently, many large U.S. department stores determine band size by starting with the measurement taken underneath the bust similar to the aforementioned underbust +0 and underbust +4 methods. A sizing chart or calculator then uses this measurement to determine the band size. [61] Band sizes calculated using this method vary between manufacturers.

Bra Cup Sizes From AA to HH

These cup measurements are only correct for converting cup sizes for a 34-inch (86cm) band to cm using this particular method, because cup size is relative to band size. [74] This principle means that bras of differing band size can have the same volume. For example, the cup volume is the same for 30D, 32C, 34B, and 36A. These related bra sizes of the same cup volume are called sister sizes. For a list of such sizes, refer to § Calculating cup volume and breast weight. Cup sizes have traditionally used a step size of 2.5cm, which is close to the English inch of 2.54cm, and featured some double letters for large cups, but in recent years some Italian manufacturers have switched over to the European 2-cm system. 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 ]
