Very high quality suit for the price! Might as well buy, then rent.
Color: Deep Grey (Stretch Fabric), Size: X-Small
I bought this for my son for his Prom, as he decided to go last minute. He weighs around 125 pounds and is about 5'11. The XS fit was pretty amazing. As the supplier says, follow the size chart on the second picture. There is also some stretch to the material and the pants have belt loops. The only thing we noticed that we didn't like is that the sleeves were a little large at the opening around the wrist. Since the cuff-links are sew on, there isn't really on easy way to adjust this. All in all, this was a great purchase and I would highly recommend YND suits.

Good buy for sure.
Color: Burgundy (Stretch Fabric), Size: X-Large
The suit looks and feels great for the price I’m 6’3 190-200lb and ordered a size XL. I’m going to have the sleeve dropped a tad bit and waist taken in. The hem is perfect and to my liking. Will be buying 2-3 in the future.

We’re happy!
For the price, this suit was great. My son is a bigger guy and when we rent tuxes, the pants always look terrible. This one, we were happy with. He usually wears a 2x in clothes but we sized up to the 3x. He’s 6’2” and prob 270. Maybe more but the vest was still a little snug.
