I'm 5"3 120 pounds I ordered a size 8 (34) my regular clothing size is a 2 .the suit looks great on. Feels durable. However it goes up very high in the crotch area, I loosened the straps but its still very high up there, but I got use to it while I was swimming, I don't think a bigger size would have made a difference, it fits a bit lose in the back area but lays flat in the pool. Overall I still like it. The material is very light, nothing like regular tyr swim suits that I use to wear.
