I wasn’t expecting much for about $50
Size: Medium, Color: Blue, Size: Medium, Color: Blue
I was in a hurry from for a casual dinner jacket for a Caribbean cruise with my 11 year old this week. I wasn’t gonna be picky. 1) it looks like 70’s leisure suit material 2) what looks like lint are little bits of white polyester thread. When picked off one of said pieces of lint, this picture with the long thread happened 3) it came folded in a manner you should not fold a jacket. 4) Its 19% linen 1% cotton but it looks 0% natural materials 5) A 40R fits me well and I’ll not be able to button this size M, it’s too small for me. It will work unbuttoned 6) I’d return if I had an option. It’s low stakes, I’ll wear it twice and never again. 7) The pictures in the ad are fair, just look at all of them, not just the first one. Overall I don’t think it should be marketed as linen.
