Regular folks like you and me can throw on a Snuggie and some sweats and hop on a plane without having to worry about a throng of photographers and fans waiting to pounce on us once we land. Sadly, poor celebrities have a much, much tougher time in life. So they've developed a very distinct style formula when it comes to air travel. As you click through, you may notice it has a lot to do with dark layers (because how else are you gonna cover up wine and potato chip stains all over your shirt?) that don't sacrifice comfort, seriously buttery leather bags, and, of course, sunglasses at all times, to make even the most thrown-together ensemble chic. The latter may also be considered helpful when it comes to throwing off the paparazzi, but come on guys, ya gotta know it's a dead giveaway, right? Because as everyone knows, only a-holes and famous people refuse to take their sunglasses off inside.
