Well leggings, a long tshirt. I usually wear leggings and a tee and then I carry my pj on my carry on so that if I get uncomfortable, I can change into my pjs. It REALLLYY helps. :) and for shoes, I wear Converse usually but if i would recommend something that is easy to take off since in some security checks, u have to take off ur shoes also. Oh and don't forget a jacket :)
If your plane ride is going to be long, try wearing something comfortable like some jogging pants or yoga pants with a comfy tee and a pair of flip flops or flats(:
comfortable clothes, easy removable shoes ... nothing that looks explosive? that is all i can think of
it does get cold on the plane but running around looking for the gate can make you break a sweat
leggings are always comfy, tshirt, bring a sweatshirt & for shoes wear flats or jandals.
What you would normally wear, if it'sa long plane ride I would wear cute sweat pants
should i wear some of the heavy stuff like jeans and a wool cardigan ?
Yup go with her Go with something That You would like to sleep in :)
wut EVER IS comfy, yet stylish
Casual and nice....
