Joan Jett sure knows how to play the role of the hard-as-nails rocker. Her smoldering gaze, sharp-edged mullet haircut and black-on-black stage costumes may be a career-long homage to bass player Suzi Quatro, however, Jett has managed to transform it into her signature style.

When the Pennsylvania native formed the all-girl group The Runaways in 1975 with drummer Sandy West, eventually adding Cherie Currie into the mix, the band's status shot up the charts with hits "Cherry Bomb" and "Queens of Noise." However, it was her cover of "I Love Rock 'N Roll" that made Jett a certified sex symbol -- both on and off the stage. 

As Jett celebrates her 54th birthday on Saturday (September 22th), we're taking a look back at the "Bad Reputation" rocker's style over the years. Vote on all her looks in the slideshow below. 

Meanwhile, get a sneak peek of the costumes from the "Women Who Rock" exhibition currently running at the National Museum of Women in the Arts in Washington, D.C.

Sometimes we wake up on the wrong side of the bed and we just want to throw on some tight jeans, a t-shirt and a ton of eyeliner. Meaning: sometimes we just want to look like Joan Jett. The lady is a true rockstar, and she has the killer style to prove it. What a reputation.
