The material is nice quality but it’s fine/thin (so not a jumper you’d choose to keep you warm!) and the fit is loose, but it’s meant to be, which I like, although the slash neckline is on the cusp of being just ever so slightly too wide for me, so it could fall off my shoulder (which is probably normal for this style anyway) or gape a bit at the back. But I’ll wear a vest top underneath anyway so it’s not an issue really.
