Bikini Top Size, US

Bikini top plus sizes are usually given in two (2) different ways, depending on brand and model:

1. Bra Size is used. Then you pick bikini bottom size and bikini top size separately. See here to determine your US bra size. Size example: Bottom Size: 2X(18), Top Size: 42C

2. Bikini top size is determined with the same size system as the bikini bottom. With this sizing system, both plus size bikini bottom sizes and plus size bikini top sizes are labeled like i.e.: Bikini Bottom: 2X(18), Top Size: 2X(18) (if you can pick bottom size and top size separately) or Bikini Size: 2X(18) (if sized as a set). Use the bikini size chart below to determine your bikini top size (same as bikini bottom plus size chart):
