I bought an M hoping for it to be a little oversized, however the collar is too wide for me to wear it buttoned, while also too flat to wear open. I expected the collar to have a degree of structure but possibly due to the knitted nature of the fabric, it was not able to provide any kind of structural integrity to the shirt. The sleeves are a little odd as they bunch up near the opening, resulting in a bunched up appearance. This makes it difficult to wear as a layer, but also not heavy or sturdy enough to wear as an outer piece. Additionally, my particular shirt seemed to have a number of loose threads along the edges of the sleeves and hems. It's both too big and too small at the same time in different places. I haven't worn it out as a result, and I'm not sure if I ever will.
I was very excited for the print but not very satisfied with the piece overall.
