Who's Wearing the ‘Stache Here?

What is it about the mustache that has made it such a cultural icon as of late? It seems I can’t go anywhere anymore without seeing a funky little hipster mustache logo on almost everything—cell phone covers, key chains, men’s clothing, women’s clothing, bumper stickers, etc. This week I saw a little girl in the grocery store wearing a mustache tank top. What happened to ponies and princesses?
