High School Swimsuit = 3180 yen ($26.95 €24.46)
My daughter bought her school swimsuit for 3,180 yen ($26.95 €24.46). It is a uniform and every student wears it. She has her school swimsuit of her junior high school, but it is not allowed to use it in the senior high school. It is a strange rule, I think.
Here is a sample of school swimsuit (link to Amazon.co.jp).
