Boys Formal suit
Size: 10 Years, Color: Champagne, Size: 10 Years, Color: Champagne
This formal suit is perfect for weddings, or any formal function. It is true to size. The pants run a little long. The material is shiny. The suit is worth the money, and actually looks like it cost more than what it did. There is not adjustable waist. You have to wear a belt with it. This outfit will make you feel rich in spirit. My son was so adorable in this outfit.
