Great for the price.
Color: Brown, Size: X-Large
I bought this vest for my brother in the Philippines. He like a vest with a fringe or tassel, and this is the only item that has it. I am rating it a 5 star because of a quick replacement for the defective item that I received at first. The materials used are thin, however, the vest still looks great. I hope they will last a bit longer after several washing.

Cheap-poorly made junk
Color: Coffee, Size: XX-Large
I needed a vest with some fringe for a costume party on 11/24/23. I looked at many others but decided on this one due to the fact it would arrive on Wednesday instead of Friday, the day of the party. I beyond disappointed in the quality and fit of this vest. I knew that it was faux leather but it was the worst faux leather type material I had ever seen. The fit was terrible, said 2xl but 1xl tops. It was probably my worst purchase ever on Amazon. Save your money and do not purchase this vest.

Nice!
Color: Brown, Size: XX-Large
A lot better made than I anticipated. Looks and feels like suede. For my needs, it was perfect for a costume. Fits well, and looks more expensive.
