The days may be growing shorter, but one thing got longer this past month. Mustaches, and lots of them. Mustaches popped up all over the world in November — with some of the best sported by celebrities from Kris Jenner to David Beckham — for Mustache November.

What began in Australia as a campaign to raise awareness of these issues has now grown to become a worldwide cultural phenomenon.
