What do you wear when you walk in to apply at a restaurant?

to apply for a job at a resteraunt; Have clean fingernails, pull your hair back in a pony tail or up in a bun. and if you just have sneakers use a magic eraser ,by MR. Clean , works great. or just adamp cloth ; what ever is confotable and doesn't look sloppy. not too much makeup. Trust me I just work in the kitchen at a very busy resteraunt and hear these thing while i'm working, so for the up and up, just be sharp and Oh one more thing ! They always criticis your purse that you are carring. Good luck!
