Bra Sister Sizing

Is the bra that you want unavailable in your size? Try its sister size! Each bra size has 2 possible sister sizes. To determine your bra sister size, move your current "number" (band size) and "letter" (cup size) by one unit in opposite directions. For example, if your wear 34C, you can also it a 36B or a 32D.

This bra sister size conversion table definitely makes things easier:

Bra Sister Size Conversion Table. Choose the Adjacent size to your regular bra size.

Although sister sizes are not guaranteed to work for all women, as we have different bust contours and body build, they are guaranteed to offer a more convenient and practical alternative to many.
