I was very nervous about buying this, just because the reviews said to go up a size. I'm 5'2 and 150 lbs and I usually wear a medium, but I ordered a L/XL. When I opened the package it said XL and I thought "greatttttt" but it fits very well. If you're looking for high quality you could try Gucci because this $25 blazer isn't for you, but the quality is very very good. Definitely go up a size, highly recommend this super cute blazer!!!!
