The When-to-Wash-It Handbook
How often you should wash: After every wear.
What to know: Treat them like underwear. “Close-fitting and oil-absorbing, these basic pieces add life to your pricier blouses, sweaters, and jackets,” says Corinne Phipps, founder of Urban Darling, a wardrobe- consulting firm in San Francisco. Wash in hot water.
Exception to the rule: Stick to the four-hour rule. If you wore a T-shirt or camisole only briefly, there’s no need to be rigid. “It’s OK to put a barely-worn tee back in the drawer every now and then,” says Salinger.
