Great for the price
Color: Dark Gray, Size: XX-Large
Looked great on my husband for a celebration of life we had to attend. Turns out we over dressed compared to most! He also appreciated the fact it was not as thick as most vest and he didn’t over heat in it. Has adjustment in the back for a better fit. I honestly could have sized him down one and it would have probably looked even better! Definitely felt it was worth the money

Bought for my sons 12 grade events. It is a nice lookiing vest he wanted to wear with his dress clothes.
It fit him beautfully. He was able to bo up the buttons with out any issues
Decently priced. It felt nice on and is dressy without being to dressy so he will get some more use out of it other then school events.
