Uniform hacks that should be taught in training

Sharing the ones I teach new joiners: clear nail polish over the hair pins so they don't slip; a stain pen and a mini lint roller in the pocket; hairspray on the inside of the collar to stop makeup transfer; roll the blazer, never fold; heels one size bigger with insoles for long sectors; and a spare pair of tights in the cabin bag, always, because the day you don't is the day you need them.
