One of the best suits out there!!
Color: Christmas Green, Size: 8 Years
I am not one who write reviews, so the fact that I'm penning this review you should know. These suits are the best, the sizing, the fit, the quality everything is perfect. I bought for my 3 sons and they all fit well, I was worried about the fit because one of my son is slender but tall so length things would be okay but waist toooo big, with this suit everything was on point. Ages: 13-14(about 5"4-5"5 have a little body wouldn't consider husky) got him size 18,
10-11(slender but a little tall for his age) got him size 14,
9yr old(average height and body size) got him size 8. Can't beat the price and for 6 pieces(pants, vest, jacket, shirt, tie, bowtie)

Great buy
Color: Champagne, Size: 6 Years
I bought 3 sizes for my sons to wear at our wedding. They are heavy duty quality material. The dress shirts are a little stiff and snug but also great quality. Would buy again 100%
