This is a swimsuit specifically for Seika Swimming School. I am selling it because my child has outgrown it. The bottom area is a bit worn, but I don't think it's see-through. The name section has been blacked out. This is a size L, but my daughter, who is a 4th grader and 140cm tall, used to wear it. For your reference. Please purchase only if you understand that this is a used item. Thank you.
