Thank you for viewing. This is a swimsuit for boys. The size is 3T. I looked it up online and it corresponds to Japanese sizes 95-100, but it felt a bit small, so I've listed it as around 90. My child used it when they were a year and a half old, and it was too small by the time they were two and a half (they are large for their age). There is a name written on it. It has been used a few times, but there are no noticeable stains. Thank you. - Color: Light blue and white wave pattern - Design: Shorts style - Waist: Elastic and drawstring - Features: Wave pattern print
