JC Chasez Style Evolution: Gelled Hair, Denim-On-Denim & More Boy Band Fashion (PHOTOS)

Boy bands of the '90s sung, danced and wooed wearing the usual uniform of baggy pants, button-down shirts with muscle tees and weird hairstyles. Hanging onto every single note of their heartbreak melodies, are we to blame for their unwillingness to shed the look that brought them so much attention? Maybe? However, we're staging an intervention starting with JC Chasez.

While in the prime of his career as an 'N Syncer, Chasez sported patchwork denim, colored leather pants and frosted tips. He then developed a much more polished style (wearing tailored suits, gentleman's shoes and a tapered haircut) during an unofficial fling with Eva Longoria. Yet, the "America's Best Dance Crew" judge has since had more than a few fashion slip-ups, begging us to ask, "Why mess up a good thing?"

In celebration of Chasez's 36th birthday on Wednesday (August 8th), we're taking a look back at the entertainer's style over the years. Vote on all his looks in the slideshow below.
