I did go by the size chart, but when I got it, it would’ve been too tight to comfortable wear with anything under it. I went through the exchange process, which was very easy, and the people I spoke with were so nice (as usual). I just received my new one, which is much better.
Definitely do yourself a favor and size up! The colors are so pretty in this, which is why I wanted to exchange and not just get a refund. Plus, I love the material they use. I sized up one, and I could have probably sized up two to be even baggier. I never usually wear the size that I sized up to, but I’m sure it has to be all about the style and cut. But, I also wanted my sweatshirt to have some fitted characteristics to it. It just can be hard buying clothing online and trying to go off of a size chart, however if something doesn’t work, support will help you out no problem. I think I do prefer the full zips, but this is a nice change for the cooler temps now.
