Love this tuxedo!
Love this tuxedo! I purchased this tuxedo in a size Small for my son to wear to a wedding. He is 5”10 and weighs 180 lbs. Everything fit well except the pants needed to be hemmed a bit. My son looked very handsome in this tux and received several compliments. Great buy!

Really slim - err on the side of caution even when using the size guide
Color: Deep Green, Size: Large
Men's Slim Fit 3-Piece Tuxedo Set, One Button Shawl Collar Jacket Vest Pants for Party, Business and Wedding
When they say slim fit, they mean it. I’m normally a large. I used their size guide to make sure I chose the right size, and when it arrived, it definitely was too small in the shoulders and the stomach (ahem). That being said, my weight fluctuates a lot, so I’m sure I’ll be able to wear it sometime. The tuxedo itself is really nice and stylish. It looks good, and even though it’s synthetic, it feels pretty good too.
