It’s okay
Wanted a neat cotton jacket for breathability - this is mostly cotton so I thought it would be ok on that front.
The shape of this jacket isn’t quite what I was hoping for though. It’s more bell bottom than the photos suggest because of how they did the pockets and the zip bulges in the same area exacerbating that shape.
The arms are a diagonal cut (from armpit to neck) and run small.
Definitely go a size up if tight arms bother you.
