Selena Gomez [1] joined the Puma [2] team for the launch of the new Defy sneaker at Paramount Studios in LA. Being the face of the brand, Selena knows how to dress the part [3] — she even rocks Puma trainers with maxis [4] when she's not at the gym. But it seems there's one key accessory Selena likes to style with her sport gear: hoop earrings.

In her campaign for the Phenom Lux [5], Selena wears an oversize pair, and her latest pick is the Alison Lou Small Jelly Hoop in white [6] ($125), a lucite design that also comes in lilac, baby blue, and baby pink. Selena is not the only one excited about transparent hoops — Bella Hadid is here for them too [7]. And, once you see how they amp up Selena's sleek leggings and zip-up combo, we think you'll quite agree it's time to invest in a pair.
