After going off of the reviews I size down from a medium to a small and it was too small. I was able to get the outfit on but there was not enough material on the tarsal area, so the outfit was pulling in the back area. This outfit is true to size so please get your normal size and don't worry about the stretchiness because your normal size will fit perfect. The outfit is fire and I'm so disappointed that I didn't follow my first mine to get my normal size. I'm not going to send it back because Fashion Nova charges you a shipping and restocking fee so it's not worth it I'll just reorder the correct size. For reference I am 5"3 150 lbs. and I wear a size 5 in jeans. 34 DD bust 26 waistline and 39 hips
