Like J.Crew’s Fenton/Fallon collaboration, sister retailer Madewell is getting in on the glam-rock jewelry action. This Jewel Box Necklace juxtaposes the right amount of tough and sweet. It can be paired with solid-colored Alexander Wang T-shirts for a put-together casual look, or with a vintage floral dress for something a little more feminine. Though the piece also comes in a hot pink or sky blue, the transparent pink version looks the most upscale of the three.
