Airport Dressing 101
Heading to the airport is like heading to the dining hall on a Saturday morning - you could go in sweatpants and Ugg slippers or you could pull yourself together (without sacrificing any comfort). The airport, aka the closest you'll probably get to Hell on Earth, is never a pleasant experience, but with some strategic dressing, you can be both comfortable and well-dressed (and a little less stressed).
Easy to layer and take on/off in case the guy next to you cranks up the air conditioning
Pants always (bare legs on a scratchy plane seat are a no go), preferably with some stretch for those long hauls. Small details go a long way in amping up a pair of basic jeans or leggings.
A statement pair elevates any outfit. The trick is finding ones that are easy to pop off to go through security and slip back on to pace the narrow plane aisles when your foot falls asleep.
