Sharp and goes well with fancy, or jeans. Looks great for the price.
Size: Large, Color: Black
As tweed Herringbone vests go, this is rather nice and fits well. I'm 5'10", medium build and the Large fit nicely. I ordered it to go with my Oktoberfest Lederhosen outfit (worn to Oktoberfest in Munich), and it worked well. It'll also work with jeans. It's not some high quality piece, but for the price, appears more expensive than what it costs.

Nicely made
Size: XX-Large, Color: Burgundy
Good vest, nice material, good stitching, not too warm. I like it for over a button down shirt.

Nice Qualtiy for the Money
Size: Large, Color: Light Blue
I originally ordered this vest in XL based on other reviewers' suggestions to up size, but I returned it for a large. Vests should fit snugly and not be loose. I'm 5"9" and 175lbs and the large was a good fit for me. The material is not as heavy as I expected based on the photos but it is not flimsy. It is well constructed with a nice liner. For the money it is a really nice item. I have nicer vests but then they cost several times what this one did. Overall, I am very happy with it.

Not terrible for the price. Not super high quality.
Size: 4X-Large, Color: Black
Not bad for the price. Fits a size smaller. I can wear it standing up, but need to unbutton it to sit down. I have very little faith in the buttons. The sewing looks rushed. I may cut them off and replace them. Brown buttons with a black vest? Odd choice. Not sure what the half moon pocket is for next to the button holes.
