Best Bet: Mini Festival Necklace

Muggy, 90-degree weather calls for a simple arsenal of cotton-jersey dresses, tanks, and tees. This cheery enamel necklace adds an understated flash of color to simple summer basics with a row of multihued triangular baubles. The gold fringe creates a light-catching accent, while the contrasting shades of the flaglike charms lend the piece an easy versatility. It’s a pretty, affordable alternative to chunky beads and bib necklaces.
