I just want to not think too hard about what I wear on the plane, so it's black leggings, comfortable black sneakers/trainers, long tunic, light black jacket with inner pockets, scarf. Good for every class, lounges, red-eyes, waiting at the gate, last minute upgrades, and working right off the plane. I change my personal item more often than my flying attire. If I'm off to somewhere like Jamaica I might leave off the scarf and carry shorts to change into at MBJ.
