Strappy-back one-piece in sparkle

This runs a full size too small. I just received the 6 and it fits much better than the 4--every J Crew suit I've owned in past 10+ years has been a 4 (or 2) so size up. And, while it is quite a high cut leg and low cut back, it is not "full coverage bottom" in fact it is cut quite small in the butt. I almost sent it back for the lack of "bottom" coverage but love the fabric and front so much I decided to keep it.

Have a couple of suits in similar style from a few years ago, both a size 4. I am generally a 4 in J Crew bathing suits (a 2 in straight bandeau styles) so ordered both a 2 and 4. The 4 just fits, cut much smaller in the back/butt than previous suits in this style but overall love it!
