Before attempting the vintage look, one should always master the rules of etiquette.

For instance. Grandma’s mint-condition Chanel shoes for the cocktail party? Perfection. Dad’s shredded Zeppelin T-shirt to same party? Disaster.

Still confused? Start with JBalducci hairclips. They’re among the few things that work just about anywhere. Made from delicate metal-and-enamel flowers that have been plucked from vintage earrings and pins, they’re not the Goodys of your youth. Picture Drew Barrymore meets Kate Moss meets the hipster you envy from afar. Pretty and versatile, they keep flyaways at bay — without sacrificing your street cred or provoking another disapproving look from you-know-who.

Just save the highly flammable poly-blend bell bottoms for theme parties.
