When you're a supermodel, you don't just have one birthday party to ring in your 21st—you celebrate all week, which is just what Gigi Hadid did. The gorgeous blonde finished her weeklong celebration in Las Vegas at Wynn's Intrigue Nightclub to celebrate the big 2–1, and her dress's skin-baring plunging neckline pretty much stole the show.
The asymmetrical satin minidress from Julien Macdonald's fall 2016 collection and her Roberto Cavalli camel stiletto boots caught everyone's attention—but so did her itty-bitty personalized necklace. The dainty accessory is a gold "Zayn" necklace by Lola James Jewelry that she constantly wears and is almost barely noticeable. Between this sexy getup and her Los Angeles party look, we think this one takes the cake.
