I ordered XL for my husband who is 6'1" and weighs 200 lbs. The pants' length was too long and we had to cut off two inches and get them hemmed. Jacket could be a little bigger in the mid section and shoulders but vest fit well. Could do without the fake handkerchief in the suit jacket pocket. Still liked the style and the color of the light blue suit.

Perfect for teens

Color: Black, Size: XX-Large

Great suit! Great quality for the price. Very impressed. Bought for my teens. Didn't want to spend a lot on something they won't wear more than a couple times before they grow again. This suit is great. A tad long in the arms and legs. But overall, its perfect. Fitting suit, but got a size larger for their comfort. Surprised at the quality, my mom was impressed and she knows suits.

Great quality

Color: Black, Size: X-Small

Fit my son perfect. Ordered XS he’s 5’5” 128 lbs. pants fit great, they weren’t too big or too long. He felt comfortable and got many complements. Tie color comes random not black like the picture.
