Perfect
Color: Dark Brown, Size: 10
Obtained for one of my grandsons to wear to his big brothers wedding. It fit him perfect and looked so nice perfect color he was so proud to be his brother's best man. The material was breathable so he did not feel to hot. If you are needing a good looking suit you will not go wrong with this company.

Fantastic!!
Color: Dark Brown, Size: 10
This is the sharp, classy look you want for your child in a child’s suit! It is a nice true fit with a classy look. My son loves this and he was happy with the fit. He is a picky little guy and I was very happy with his response to the fit. The pants had a little glitch but that's ok! I’m so impressed.

First wear ripped down butt seam
Color: Champagne-6pcs, Size: 14, Color: Champagne-6pcs, Size: 14
The color is darker in person, which is annoying because we were looking at the color specifically when purchasing. Look at reviews for what the color looks like. We purchased the “Champagne” colored suit.
Size 14 works for my 13yr old.
Good quality overall. Just a bit disappointed about the color difference.
UPDATE: My son wore his suit for the first time to acting class, and while moving in a bending motion his pants ripped down the butt seam. I hope this was simply a fluke incident and that I can easily repair it. I said when he sat down it ripped more. A bit disappointing. He wasn’t doing lunges in his suit.
