Sway Alert!! This is a beautiful suite!
Color: Beige, Size: 5, Color: Beige, Size: 5
This suit fit great my son loved it. The quality is good. My son is five about 40 inches tall around 40 pounds. He’s very slim but the length was great. The suit jacket fit well. The pants waist were a little big, but the adjustable strap helped with that, but the fit overall was great . I would purchase a suit again in a different color.
