How can I make my manicure last longer?

—Emily Berry, Scottsboro, Ala.

Bobbi: First, keep your nails short so they're less likely to knock into anything. Second, use a good-quality polish. (I've never had a problem with Essie polishes.) My manicurist, Roza Israel, also suggests reapplying a top coat every night before bed to make the polish last longer and keep it looking shiny, too.Try Essie Super Duper Top Coat ($8; ulta.com)
