On July 20th, After School's new sub-unit, 'A.S. Blue', finally unveiled their debut music video for "Wonder Boy".�As the unit is in charge of the 'innocent' concept, fans were surprised to see the girls donning garter stockings, which is usually associated with a sexier image. In the music video, the ladies were seen wearing a 'pajama lingerie look' involving a blouse, hot pants, and garter stockings.�Netizens thought that the look was a bit suggestive for a unit that's going for the innocent concept and raised a bit of controversy over the issue. Pledis spoke up on the issue by explaining, "It's not a garter belt but a 'leggy look' knee-socks fashion.�In order to improve the style, we added a white connecting string from the pants to the stockings."
