In typical Fashion Nova fashion, the sizing is off. This fabric is very stretchy but I knew this was not going to fit just taking it out of the bag. I bought a size M. I am 5'8 170lbs 34 DD. I probably could have gotten away with the tighter fit because of the stretch, but I could not button up over my boobs. I am returning and paying the return fee, will try rebuying the large. Hopefully this will work out. 🤞
