"Your nails can be an accessory for your flowers and your ring," says Lippmann, who pairs sheer ivory with platinum polish for a chic French manicure (shown here: Lippmann Collection A Whiter Shade of Pale with Stardust on the tip). Sheer ivory, pink, and beige are all pretty options for the main color; choose silver or gold for the tip, depending on your ring.
Good to know: When choosing a metallic shade, steer clear of polish that contains big chunks of glitter. The end result should be delicate, not funky. Platinum Boxter ring with Asscher-cut diamond set in micro pavé-mounting and band (2.86 carats), $36,000, by Daniel K.
