"Bow ties, trim suits in gutsy shades, saddle shoes, smart casual attire -- there's no look or flourish he can't pull off," GQ wrote of Criss' style street cred. Of course, getting to the top wasn't easy! Criss had some tough competitors along the way including actors like Miley Cyrus' boyfriend Liam Hemsworth and his own on-screen boyfriend, 'Glee's Chris Colfer.
Music stars on the list include the pompadour prince Bruno Mars, rappers Kid Cudi and Donald Glover, aka Childish Gambino, and swag king extraordinaire Justin Bieber. Jonas Brother Joe Jonas came it at No. 4, beating out younger bro Nick Jonas, who earned the No. 6 spot.
Gwen Stefani and Gavin Rossdale's son Kingston was the youngest member of the 30 under 30 club at just five years old! Do you think Darren deserved the GQ honor? Check out the full list of the most stylish men under 30 here and Tweet us your thoughts @aolmusic!
