There's nothing like outdated dating rules to put things into perspective. From do wear a bra to don't look bored (even if you are), vintage advice typically manages to be useless, degrading, and hilarious. PBH3 found a dating guide from 1938, complete with pictures that are every bit as bad as the advice. Get a breakdown of dos and don'ts — heavy on the don'ts — after the jump.
Dress in your boudoir to keep your allure.
Put makeup on in private, not where he can see you.
Wear a bra, especially if you need one.
Be careful your stockings aren't wrinkled.
Talk about what he wants to talk about.
Caress him in public. It's embarrassing!
Talk to the waiter; men deserve your undivided attention.
Look bored, even if you are
Get your lipstick on his handkerchief
Talk while dancing, "for when a man dances he wants to dance."
Sit in awkward positions.
Cry, especially in public.
Use the rear-view mirror to put makeup on; he needs it to drive.
Drink too much. While some girls get clever, most get silly.
