    Not a great shirt
    Size: Large, Color: Pink
    I didn’t like the material, and it didn’t fit. It was listed as slim fit but was definitely not.

    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!
