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.

Appearance nice, fit is a little bulky on the jacket.
Color: Beige, Size: X-Small
It looks very nice. The pants fit very well for my 5' 8.5" son with long legs. The jacket was a little bulkier. We will try to tailor it a little.
