In Fashion Nova, and really any other brand, I can be a M or a L. I am 5’10, curvier athletic build, 11-13 in jeans and weigh about 205. I was skeptical of size but could only order a M because the large was out of stock and I’m glad I did! The material is thin but also stretchy. I loved the color and both the top and bottoms fit great in a M. I cut of the random strings hanging down and it’s a cute night out outfit.

This set is so cute. It's just as pictured and the sizing was perfect. The material is soft and stretchy.
