Great value for a one-time event! Perfect for graduation.
Color: Black, Size: Large, Color: Black, Size: Large
I bought this suit for my son's graduation, and it was exactly what we needed. Since he will probably only wear it once, I didn't want to spend a fortune at a high-end department store. For the price, the quality is surprisingly good; it looked sharp and he received a lot of compliments during the ceremony. We ordered a size Large (L) based on their sizing chart, and it was true to size and fit him perfectly. The fabric is lightweight but doesn't look cheap at all, making this a fantastic, excellent cost-benefit choice if you are looking for an option for a one-time event. Highly recommended!

Great for the price.
Color: Black, Size: Large, Color: Black, Size: Large
I’m 220lbs 6’1 athletic build. Arms/back couldn’t fit inside the jacket. Pants and vest fit fine though. I honestly should get stuff tailored considering my body competition. Good quality for the price worked for me.

XL sized suit review
Color: Light Blue, Size: X-Large
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.
