100% cotton For ages 3-4, size 100 Length: 90 cm Shoulder width: 40 cm Sleeve width: 27.5 cm Sleeve length: 49 cm There is a stain near the hem that won't come out even after washing. The sleeves are relatively long, and since it's not seersucker fabric, it's cute as an outing yukata. It can be extended by 10 cm if you lower the waist adjustment.
