Between back to school shopping and fashion week, September is truly the month of fashion reinventions and celebrating personal style—and who are more stylish than our resident reigning pop stars?

PopCrush Best Dressed is a month-long competition to determine the ultimate style stars of 2017!

Since departing One Direction to pursue his own music, the U.K.'s Zayn Malik has solidified himself as a style star to watch, even going so far as to launch a collection with Versus Versace. Across the pond, K-pop kings EXO are as equally revered for their edgy, coordinated fashion looks, both onstage and off.

The battle begins right now: Place your vote between Zayn and EXO for 2017’s Best Dressed! Round 1 ends Monday, September 18 at 11:59 p.m. EST.
