Just commenting to say that you don’t need to size up! A lot of reviews talk about it but my true size (even slightly smaller) fits great! I’m 5’1 and normally XS on top, S on bottom, but the XXS/XS was on sale so I decided to take the chance even though several reviewers say the sized up. I think it’s great I don’t think I’d want it to be any bigger. It also looks nice and is cozy!
