Fashion nova clothes are super stretchy so most of the time I get away with it sizing down one but this romper, you should definitely go with your normal size due to the material not being as stretchyI’m not really into reflective clothing but I’m tryna get myself into different fashion and this romper was ittttt. 37” bust, 31” waist, and 45” hips, 180 lbs, and I purchased a Large.
