Forgot to shave or trying out a new look? Kicking off Mercedes-Benz Fashion Week in NYC, Justin Bieber brought his swagger and a new signature hair 'do . . . on his face. The 19-year-old singer sported a patchy, peach-fuzz mustache at the Y-3 Spring/Summer 2014 runway show on Sunday, Sept. 8.

The "Believe" singer gave photographers a close-up shot of his new mustache while sitting front row during the show. Bieber paired his manly facial hair with black leather pants, a gold-trim V-neck black shirt, white sneakers and dark shades.

In addition to the mustache, Bieber also sported a new hairstyle that was reminiscent of the side-swept, shaggy 'do that he was known for at the start of his career in 2008. The teen heartthrob styled longer bangs in the front, which he pushed to the side.

The on-again, off-again boyfriend of Selena Gomez drastically changed his hair for a "mature" short cut in 2011 because he "wanted to change it up." His chopped locks were then auctioned off for a whopping $40,668.
