Play some great music! I'm a fan of Bing Crosby and The Puppini Sisters. Both have great holiday albums out for your holiday party.
Assemble some great party favors. A tube of drug store red lipstick is a great touch. Add a string of cheap faux pearls for some glamor. (Forever 21 has them for ~$2). A sassy Anne Taintor magnet is a great reminder that vintage glamor is accesible every day!
