This tuxedo set is so beautiful. The red is extremely striking and is sure to grab everyone's attention. I ordered a size L, as I am on the cusp of Medium and Large. The pants fit very well, and they have some adjustment points around the waist in case they need to be let out a little more. Also, in the waist band is some elastic portions, which make finding the perfect fit something you won't have to think much about.--- they will stretch with you. The jacket feels like it is custom fitted by a tailor. The quality of this tuxedo, considering the price point, is exceptional.

Size up at least once or twice if you buy these

Color: Black-satin, Size: Medium

I really wanted these pants to work because they actually look very nice and the material feels decent for a tuxedo pant. However, the sizing is completely off. I normally know my size pretty well, but these arrived and were way too small. I ended up reordering two different pairs in larger sizes trying to find the right fit, and even then, I couldn't get it quite right. Since I was in a major time crunch for an event, I eventually had to give up because I didn't have the time to go back for a third pair. It is a shame because the flat front style is exactly what I was looking for and the functionality of the clasp and zipper seemed solid. The value for money would be great if the fit was consistent, but the headache of returning and reordering makes it tough to recommend unless you have plenty of time to experiment with the sizes. If you decide to grab these, definitely plan on ordering at least one or even two sizes larger than what you usually wear. They have a nice professional look to them, but the durability of the fabric doesn't matter much if you can't actually get them on.
