If you don't like your clothing to fit tight, then this blazer is not for you. I, on the other hand, prefer my clothes to be tight. I purchased this in a size Large, and so glad I did. Usually, I can get away with a medium at times, but I went ahead and got a large. It fits me perfectly, but there is no room to spare, so I won't be able to layer it with anything other than a tank/sleeveless type shirt. Also, it's not friendly for those with a larger bust. I'm a 36B and this blazer sits right on my skin.

usually xs or small but got a small and it was to small and tight should’ve sized up
