However, if it were me (as a bloke) I'd wear a suit, shirt and tie and a sensible pair of black shoes. For a woman, I guess something like a trouser suit or a skirt and jacket + blouse type thing. But that's just my opinion.
Good luck Lucy. Just out of interest, is it pilot you're going for or cabin crew?
