To measure bra size, you need two key measurements: the band size and the cup size. First, measure your underbust (just beneath your breasts) to determine the band size; round this measurement to the nearest whole number and add 4 or 5 to get the band size. Next, measure around the fullest part of your bust to find the bust measurement, then subtract the band size from this measurement to determine the cup size (each inch difference corresponds to a cup size, e.g., 1 inch = A cup, 2 inches = B cup). Combine the band size and cup size to find your bra size, such as 34B.

An 85 cm bra size typically corresponds to a UK size 38 or a US size 38B/C, depending on the cup size. The number represents the band size, which is the measurement around the ribcage just under the bust, while the letter indicates the cup size. To find the equivalent size in other sizing systems, it’s essential to consider the specific cup size as well.
the average size is a b cup or a c cup
To go from a 38G to a 36 cup size, you would typically go down one band size and adjust the cup size accordingly. A 38G translates to a 36H, as reducing the band size usually requires increasing the cup size by one letter to maintain the same volume. However, sizing can vary by brand, so it's essential to try on different bras to find the best fit.

This will depend on many factors, but if you can measure the band, that would be your number. If you can fit the bra band on someone or something and stuff the cups to be full, you can measure the center of the cup. Subtract the band measurement from the cup measurement. For every inch you add a cup size. 1"=A, 2"=B, 3"=C, etc. Of course this is assuming the bra is new and is not stretched out of shape. If your trying to find out a persons bra size I recommend they get a custom fitting (not a department store fitting) to find the correct size.
