The Singapore Air female flight attendants uniforms have a pocket for a pen sewn into the inside-front of the outfit, so when you ask to borrow a pen to fill out your customs arrival card (which is stamped "death to smugglers), she leans forward, reaches into the front of her dress and pulls it out from her cleavage. No joke.
