Your swimwear questions, answered.

Can I return or exchange swimwear if it does not fit?

What is the cup size range?

Are the cups in all the suits removable?

Should I fit the one-pieces for my chest or for my bum?

Fit to your cup size for the best support. If there is a dramatic difference between your underbust and hip measurement, we suggest trying the suit on with the sanitary strip intact and tags attached. That way it can be returned or exchanged for a better fit if needed.
