Men’s Casual Linen Blazer – Halloween Edition
Size: Small, Color: Light Blue, Size: Small, Color: Light Blue
Bought this for my 15-year-old daughter’s Halloween costume—she was the blue tux half of Dumb and Dumber and absolutely nailed it. The blazer looked exactly like the photo and totally completed her look. She’s 5’0” and 95 lbs, so the smallest size was still oversized (as expected for a men’s cut), but it worked perfectly for the costume’s vibe. Quality was solid for the price, and it held up through a night of candy, chaos, and photo ops. Verdict: Not tailored for petite teens, but if you’re going for comedic flair or costume gold, it’s a win.

Nice sport coat
Size: X-Large, Color: Khaki
The quality is good but the beige color had a pinkish tone to it that I didn’t care for so it was returned. It’s a nice sport coat otherwise for the price! My husband wears a 42 long but the XL fit well.

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.
