back to the topic- i hate wearing a sheital while flying (i hate wearing a sheitel bechlal) so i use a baseball cap. when the lights go out i take it off and put up my hood which brings me to the op- i wear a hoodie, leggings, skirt, and gym shoes in flight. i've also worn my swimsuit underneath in the past. hub wears his uniform. black slacks and white shirt with whatever shoe takes up the most room.
while vacationing i wear a cap or mitpachat. then again, that's what i always wear unless i'm at work or a simcha
