I got the S/M and it’s too big. And it’s a crochet pullover so there’s no adjusting the size. For context I’m 5’1 and 135 lbs with a medium bust. If you’re my size or smaller I recommend not buying unless you plan on modifying it. I haven’t decided if I should return it though because it’s just soooo cute. I may keep this top and pin it to a better fit.
