Best Bet: Ombré Bead Necklace

The right accessories can turn a cotton tank or simple jersey dress into a pulled-together outfit. This ocean-hued ombré necklace by Danielle Stevens makes a beachy accent for summer. The turquoise, sea-glass green, and aqua strands are made of lightweight wooden beads, so it's easy to throw in a duffel for a weekend getaway (and the joined single clasp means they won't get tangled on the way). It's a feel-good piece that works just as well with a bikini as a maxi-dress.
