Im 5'8'' And 125. I Fit Most Of The Smalls On FN. But This Dress In Particular I Wish I Got An XS. The Top Was A Bit Loose Because I Have Small Breast And The Bottom Was Heavy With Material Causing It To Drag The Floor. It May Fit Better For Someone With Bigger Breast And Hips

I ordered a 1x but the top part of the dress is for a very small breast woman while the bottom was a size too big. I will have to find a woman who is a size B cup but a size 20 in jeans. That's an odd shape but I only paid $12 for the dress so not returning it
