UNIQLO Knit (size 100) 97% Polyester 3% Polyurethane My child wore this once for their entrance ceremony when they were 3 years old. I think it's in beautiful condition. I put a shirt underneath this and paired it with black pants... that's how I dressed them that day☆ It's also stretchy, so it seems like it was easy for a small child to wear. Recommended for formal occasions like entrance ceremonies☆
