I fly a lot (about twice a month) and usually on flights that are 5+ hours of sitting in small seats at a time. I've been trying for a while to find a comfortable travel outfit - usually after that long, the waist on whatever bottoms I'm wearing start digging into my waist and hurt/itch and that my bra straps start bothering me. A bunch of people have recommended that I wear workout clothes/yoga pants, but I'd really rather not do that. So what do you guys usually wear when you expect to be sitting on a plane for a long time?
