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.

I bought this suit set for my grandson, and it exceeded all expectations. The fit was absolutely perfect—true to size and very flattering. The material feels high-quality and well-made, with attention to detail in the stitching and finish. He looked so sharp and felt comfortable wearing it, which made the occasion even more special. Highly recommend this set for any formal event!

Great value
This suit was the cutest for my son’s graduation. He is slim enough to fit a 5 but tall enough for a 6. I did get size 5, it fit good, except the vest was a bit on the smaller side. Luckily my boy is skinny. The quality is great. Definitely get your moneys worth. The only con I have is that this item was definitely worn before & likely returned to Amazon. The shirt was wrinkled and not packaged like a “new item”. It was in a regular plastic. You can see in the photo the wrinkles on the shirt sleeves.
