Perfect fit
This fit beautifully and needed no alterations. I ordered a medium just in case but didn't need to try it since the small fit so well. I have an athletic build and not very curvy but this gives me a bit of a figure in the waist especially with shape wear thong. I don't know my hip size but I'm more on the slender side. For reference I wear size 2 or 4 bottoms in lululemon and size 27 jeans.
