Nice looking suit!
Size: Small, Color: Black, Size: Small, Color: Black
This suit fits my son perfectly & looks great! He is 5'9" & 145 lbs and I ordered a size Small. I was worried it would be big, but it looks & fits great! He'll be wearing it for his sister's wedding in the fall. We got a burnt orange vest, tie & pocket square to go with it. I can't speak to how wrinkle resistant it is since he hasn't worn it yet. My only complaint is that the breast pocket appears to be a fake pocket, so we cannot put a pocket square in it.

A good First Communion suit
Size: 6, Color: White, Size: 6, Color: White
This suit looks and feels really nice even though it’s not 100% linen. My son is an average size 7 year old, but I got a size 6 so that the fit would be nice and snug and not loose and baggy. It was the right choice. Comes with a bow tie which is nice, a tie (which is very cheap and poorly made) and a pocket square.

Very stylish💜💜
Size: 6, Color: Light Blue, Size: 6, Color: Light Blue
This little suit for boys is very stylish. I bought it for my grandson for a wedding occasion and it looked very nice. The fabric is not too thick so for the summer wedding it was great. I pick the blue color and it looked fantastic!
