Coat is very nice - - I didn't expect it to be as nice as it is!
Size: X-Large, Color: Black
This coat arrived promptly, and I am very pleased with it. Very wrinkled, but it ironed up real nice. My husband is usually in between a Size L and an XL. I ordered an L first and it was too tight, so I returned it and ordered an XL and it was too big, so I would say the sizing is spot-on. I was able to take up the sides enough that it now looks good on him. The fabric and construction seem sturdy. He is wearing it to an Edgar Allan Poe function, and I think he will look fabulous.

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.
