On Hailey Bieber: 16Arlington dress; Gia/RHW Rosie 14 Linen Sandals ($480); Balenciaga sunglasses

Hailey Bieber's taste in shoes is pretty impeccable. Her style is so widely followed that she's capable of turning a shoe style into a trend and new shoes into It shoes practically overnight. I'd say the latter is the trend in this instance.

While she was in New York last week, one of Bieber's many great looks for her trip included a 16Arlington dress that she paired with heels from a brand she's worn on repeat occasions: Gia Borghini. (This particular one is from the designer's most recent collection with Rosie Huntington-Whiteley.) The shoes are a pair of black high-heel mules made of linen, featuring an angular square toe and a single strap at the base of the toes.

Given Gia Borghini shoes and their track record with celebrities, the fact that her shoes aren't quite as expensive as other luxury It shoe brands, and that Bieber wore them for a high-profile outing last week, I'm predicting that the Rosie 14 shoes are going to be the next It shoes. Shop them for yourself below while you can—they're already selling out.
