Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.

Great vest for a great price!
This vest is more slim fitting, stylish, & flattering than many vests. It fits as expected, but it is adjustable in the back, so you do have some wiggle room to tighten & loosen it if you’re unsure about the size. My son wore this vest to homecoming. He is 5’ 10” & 150 lbs, & the size small was a good fit.
