Great style; unique; fits well.
Size: Medium, Color: Gray
Love the style and the fit. I get a lot of complements wearing this. With only three buttons, wearing this outdoors in the cold might not be practical. Other than that, I like it. I went back and ordered a second coat but in a different color.

Nice, mid-length trench coat for style and comfort...
Size: X-Large, Color: Black
I like this mid-length trench coat. The seams are good (on the one I got) and the style is perfect for the office, semi-formal occasions and all-around wear. The fit is good, and the only complaint I would have is the sleeves are a bit too short for my long arms.

It’s ok
Size: X-Large, Color: Gray
This jacket is OK. I bought it for my boyfriend because I really like the coat collar but once it got here. The front fits well but I think the back needs a little more tailoring because it kind of sticks out but he really liked it. He said he could put a heavy sweater up under it. That way he can get more ware out of it. It’s OK.
