With grunge and gothic leanings, her overall fashion stance is far darker than that of her model sister’s and the trendsetting crew she rolls with. Bella’s more likely to kit-up in all-black leather than be found in a cute dress on any given day of the week, and after discovering her über-stylist on Instagram, we can see why the two are a match made in heaven.

Meet Elizabeth Sulcer, the powerhouse behind many of Bella’s most memorable looks. She’s a petite blonde rock chick, who you may have already spied in selfies alongside both Hadid and the roll call of her other high-profile clients. Elizabeth is particularly well-connected to the industry’s key models and influencers—Josephine Skriver, Caroline Vreeland, Adriana Lima and Elsa Hosk have all sought her wardrobe expertise. Sulcer’s work outside of the A-list circuit includes gigs with the biggest photographers, brands and mags (Vogue and Numero, to name a few)—and, as if she couldn’t get any hipper, her career started at Alexander McQueen, where she played a part in many of the brand’s most groundbreaking, pivotal moments.

As sure as day follows night, it’s a safe bet then that Elizabeth’s personal style is just as covetable as her clientele. One look at her gym attire (crop top, nerd specs, major abs), and you’ll no doubt be reminded of the kind of girls she works with, but from on-set ensembles (sweatshirt, skinnies, perfect pose) to Paris in night-out party dressing (glitzy, plunging, body-con), there’s much more to Sulcer’s skill set.
