We offer this chart as a guideline. Check your measurements first and then find the right size for you.  You can order different size top and bottom.  If you have any doubts please email customercare@zwimzuit.com.

If you have a small bust measurement but a large cup size then order the next size up.  For example, if you measure 33 ins bust but are cup size D then order the next size up - Medium.

The Charlie is a snug fit for support so order the next size up if you prefer a looser fit.

* Please note: > means 'Greater Than'.
