This ended up being a great purchase. My son chose this suit for prom. He made sure to check the reviews and size chart and was very happy with the fit, quality and overall look. He's 6'1", 170 lbs and got a medium. It was perfect.

Great suit at a great value
Size: Large, Color: Black
I have ordered several other suits from the seller for my three boys over the last several years for either their prom, special events and graduations. The fit and value are wonderful. I would definitely recommend this suit if you want something that is classy looking, but won’t break the bank

Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.
