I'm so glad I purchased this suit! It fits so nicely!
So here's the stuff us plus girls want to know: I'm 5'6\\\", weight 187lbs, DD cup size and I purchased a size 18. It fits the chest area perfectly. The cup inserts are firm, not the thin easily foldable ones I usually yank out immediately.
The shorts I'm not going to wear- but I walked around the house a bit in them and was pleasantly surprised they remained in place. Ie. Did not get gobbled by my thighs.
I just prefer a different tan line, but they fit very nicely around my 53\" hips.
