This is a replica, but it's not a costume; it's made with fabric and sewing by a school uniform manufacturer. It's a genuine, brand-new sailor suit. The color is a standard navy blue. The size is: top 200cm (shoulder width 47cm, bust 121cm, length 54cm, sleeve length 63cm), skirt waist 100cm (fits w96-w104), length 40cm, and the scarf is brown. 100% polyester. The skirt can be exchanged for a smaller size.
