Wiz Khalifa has an IDGAF attitude about his sense of style. He's worn loud prints, leather vests, and some pretty outrageous things in the past. But this year, the Pittsburgh rapper developed a rock n' roll, grunge look. 2013, especially the last few months, has also been all about Kokon to Zai for Wiz (wifey Amber Rose also rocks the London brand on a regular basis). It'll be interesting to see if he keeps this going in 2014.
