The predominant theme of spring accessories was bondage, which peeked through in the details. Naughty elements appeared at several shows: chains, spikes, lacing, and ties that bind. Heels were tougher, especially at Vera Wang and Rodarte (watch for spikes), and the va-va-voom factor was upped at Narciso Rodriguez, Derek Lam, and Phillip Lim. On the other end of the spectrum, Calvin Klein showed easy-to-wear platform wedges, and Marc Jacobs, shockingly, had flats. Bags were colorful, beaded, chained, roped, and tasseled.
