Sizing - Signature Set

Signature Full Cup Bikini Top

Order your usual Core Swim size.

Wear our Halter style?
Order one cup size larger in the Signature Full Cup. For example, if you wear a 36E in our Halter, choose a 36F in the Full Cup.

New to Core Swim?

Cup Size: For full coverage, we recommend choosing one cup size larger than your usual bra size. For example, if you normally wear an E cup, choose an F cup in this style.

Back Size: If your usual bra feels comfortable when fastened on its tightest hook, choose the same back size in Core Swim. If you normally need to wear your bra on its loosest hook, we recommend going up one back size. For example:

• Wear a 34 comfortably on the tightest hook → choose 34
• Wear a 34 on the loosest hook → choose 36
