Just here to repeat what other reviewers have said- this hoodie is so great that I immediately turned around and ordered another one. I usually wear a small in tops but often size up to accommodate broad shoulders and/or layers. I got a medium and I’m very happy with the sizing. A small would have worked fine but I like a little room. It does not look oversized at all and has a svelte (not boxy) profile. Very stretchy cuffs, easy to pull up the sleeves. The stretchy side gussets are some smart garment engineering. The thumb hole construction results in a wad of fabric at the end of the cuff that’s a little annoying, but I can fix that, and most folks mat not notice it. Fabric is soft and cozy feeling. As others have said, the hood is a little shallow, especially for folks who pile up their hair, but it isn’t a deal breaker for me. Time will tell its durability!
