suit
Size: 12, Color: Beige
Very nice suit set. size 12. seems to fit as expected. I love the quality. It does have multi colored thread, as it is not solid.

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!
