Impressive Quality for the Price
Size: Medium, Color: Navy Blue
Wow this suit exceeded my expectations! The sizing chart was accurate and the fit was great. The material felt soft, smooth, and surprisingly high quality it honestly felt much more expensive than the price we paid. I also liked the ample amount of pockets inside the blazer. Overall, a great value and perfect for a polished look without spending a lot. Highly recommend!

Very nice well made suit
Size: X-Small, Color: Black
This is a very nice suit. Well made, from good material. I was so surprised based on the price I didn't expect such a great quality. It fits my son very well, he is very slim. Real value for money as it looks much more expensive that the price I paid for it.

Good quality
Size: Medium, Color: Champagne
I am shocked how nice the suit is for the price. I was expecting the pants to be slimmer, but they still fit my husband great. The only discrepancy is the suit is a darker tan than pictured.

We love the Lorenzo bruno brand!
Size: Medium, Color: Black, Size: Medium, Color: Black
Fit perfect!!! He looked so handsome! The material is great, durable ans will last awhile. It hung in the closet for a couple weeks before he wore it. The pockets on the jacket are fake. But the ones on the pants are real.
