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 185cm (shoulder width 44cm, bust 112cm, length 51cm, sleeve length 60cm), skirt waist 85cm (fits waist 81cm-89cm), length 40cm, and the scarf is brown. 100% polyester. The skirt can be exchanged for a smaller size.
