As for COS I've never handled it but most of it is pretty bland. And I really dislike the layered knit thing going on in a lot of what I'm looking at on their website. But if I saw it in person maybe I'd be all up ons.
EDIT: And I have the real white painted sidezips so that and anything else in this H&M collection can fuck right off. I just about molotov'd my local mall when I heard that, fuck H&M collabos. The Lanvin one I could stomach but this makes me want to kick whoever's idea it was in the junk really hard.
