There's a fashion craze that's currently the rage ine Japan. This "fad" may be coming here, so I feel it's my duty to clue you in, so you don't have a heart attack when it hits the streets of the USA.
What you see are not see-thru skirts. They are actually prints on the skirts to make it look as if the panties are visible! Gives a whole new meaning to "Japanese Prints," doesn't it?
