For reference, I’m 5’3” 171 lbs, 34DD-30-43. I do work out and have somewhat of an athletic build but still curvy. I’m normally a size medium in blazers, I read the reviews and sized up to a large. I wish I would have stuck to my normal size. The large is a little to big and isn’t a fitted look as I would like. Unfortunately a medium is now sold out. I may decide to keep it and wear it as an oversized look. The blazer is super cute though. It does have silver/shimmer lining that you definitely notice more than the model pic shows but still cute.
