I purposely ordered a size up because I have a larger chest.  The suit is quite large in the body but has very little chest coverage.  I'd say this is best for A/B cup women with a fairly straight waist.  Even then, you may have too much fabric in the seat.  Probably a good fit for triangle shaped women.

Fit aside, the suit is quite attractive.  If it fits you, it'll look great.

I have to send this back and get a size larger

This suit did not fit me right--I'm a size 14 and got a 14. It didn't fit my coworker right either and she's a size 12. It seemed there was too much strap and not enough suit. Widthwise it was too big, lengthwise it didn't cover my chest.
