Better than expected
Color: Black, Size: X-Large, Color: Black, Size: X-Large
I took a chance hoping for the best and the three piece set was better than expected and WAY more affordable than renting one. Fit my son well, who is about 215lb 6ft tall. A little snug at the belly, but great fit, zipper up fine, came with extra buttons. The material felt of decent quality and looked like a rental. My son got to fit in for his prom at a reasonable cost and good appearance without breaking the bank

GREAT suit for the price.
Color: Black, Size: X-Large
Amazing suit. Ordered an XL for my husband when we got it. Pants were very long and a little big on the waist, so we took them to get tailored for a more fitted look.
I don’t like that the “pocket square” is sewn in but, it can be tucked down, so we did that and added our own that matched the tie we ordered separately.
Overall, good quality for the price. We have not washed but we do take it to the dry cleaners.

Quality vs Representation
Color: Black, Size: Medium, Color: Black, Size: Medium
Please check clothing due to finding the blazer a bit dirty as if someone wore it with Cat hair and dust along with a dead bug and smelling a fishy smell. We ordered in advance to take it to the dry cleaners for additional wash before using. Quality is great material; tie not included be sure to measure before purchasing to avoid any tailoring.

Earned its 5 stars!
Color: Dark Grey, Size: X-Small
My husband has a thin frame and struggles to find dress clothes that fit well without breaking the bank. Since the size measurements were very detailed, we decided to take the gamble and hope for the best. This is genuinely the best fitting suit he has ever owned. It looks custom tailored. The material is great quality and the price point is even better. We suggested this suit to our groomsmen and were delighted to see it well accommodated a variety of body types. My husband loved his suit so much we bought him one in another color and had great success with that order as well. HIGHLY recommend this suit set!

Quality suit at an amazing price!
Color: Black, Size: Large, Color: Black, Size: Large
This suit was perfect for my son’s senior prom. Quality material and fit him perfectly! This was ideal when you don’t want to rent a tuxedo, knowing he will use it again and again. He looked so very handsome.
