Why don't you take a bath in a swimsuit that is more embarrassed than naked?

This time, I visited the Yamanaka Ko spa which was crowded with the female student such as the graduation trip to the picturesque athletic woman in the club activity camp. There were many hallowed swimsuits that were prepared in the dressing room that thought it was ordinary swimsuit. It is a swimsuit, and the important place is not able to hide it. Can you clear it?!?
