Looks like Australian boy band, 5 Seconds of Summer, may be the reason behind a clothing company’s recent success.

Since the band released their smash single, "She Looks So Perfect", American Apparel’s sales have been up by 10% because of the song's lyrics,  "You look so perfect standing there, in my American Apparel underwear."

According to Billboard, the company, whose stock has fallen 49.2 percent since the start of 2014, donated 40 pairs of briefs for the band’s music video released earlier this year.

Iris Alonzo, a spokeswoman of American Apparel, says that she has no idea if the company’s success is attributed to the song but the increase in U.S. sales is unexpected.
