We are flying to New York next year (my first time out of Europe) and are lucky enough to have enough airmiles to fly Virgin upper class.
I know this is really shallow and no one else will care but what should I wear that is really comfortable but smart bearing in mind I'm normally a Sainsbury's clothes type person. Was thinking something like yoga pants, long sleeved t shirt and soft long cardi with flat shoes but really don't want to look like I don't belong.
