Nicki Minaj isn't going to let anyone box her into one musical genre, and the same can be said for her style. Filled with raunchy lyrics and sex appeal, the Trinidad-born rapper's debut mixtapes "Playtime Is Over" and "Beam Me Up Scotty" immediately drew comparisons to Lil' Kim. But since then, the 29-year-old has managed to create her own lane in the male-dominated industry, hoping to inspire young girls (and Barbs) around the world as she told MTV News, "Whether you follow Nicki Minaj's blueprint or not, just don't be afraid to experiment and don't allow people to knock your hustle just 'cause it ain't something that you're used to seeing."To celebrate the release of Nicki's sophomore album "Pink Friday: Roman Reloaded" on April 3rd, we take a look back at the rap star's style. From rainbow-colored wigs to bubblegum pink lipstick to Harajuku-inspired costumes, check out the evolution of this style icon.
