Good quality vest for the price
Color: Navy, Size: Medium
This vest was purchased for prom, arrived on time and the color was as advertised. My son is 6ft2 and weighs 152lb so I purchased a large size and it fit him perfectly. This vest looks amazing for the price, very affordable and good quality for something that will not be worn daily. My son said it was very comfortable and it looked good.

Looks and fits well
Color: Black, Size: Large
More than I expected, frankly. It is well constructed, fits well, and looks really good. I wear it with my tux instead of a cummerbund. It works and looks better, and I never have to worry about the stupid cummerbund ending up around my knees.
