Fits the lanky teen!
Color: Burgundy, Size: 3X-Small
Nicer than expected. I really appreciate them carrying auper-slim sizing for my tall, skinny teen who can't find suits that don't have a >32" or larger waist. He has a 22" waist.he still needed a belt, but the xxxs fit him well across the shoulders and in length!

Nice Suit
Color: Black, Size: Large
I wasn't sure how well it would fit, but it fit well. The pants are stretchy, and a little shorter than I wanted. But it looks really nice and I got a lot of complements on it for New Year's Eve. I wish they would let you mix and match the suit jacket and pants.

Nice and sturdy fabric!
Color: Black, Size: XX-Large, Color: Black, Size: XX-Large
This is a very nice suit with sturdy fabric. I am a plusize female so I sized up since I thought it was cut for a male. It fit perfectly but arms needed hemming. I purchased it for a Great Gatsby theme event, but will wear it as I do any other suit in my wardrobe.

Spiffy suit for any age.

I purchase this suit for my son's high school fraternity show. He said that it was very comfortable, not to mention my son looked very handsome and daper in it. I love how fast it was shipped and the size was on target.
