Three years ago, Chloe and Halle Bailey were performing Beyoncé covers for their avid Youtube following. Now, signed to the singer's Parkwood Entertainment label and fresh off an appearance in her Lemonade concept album, they regularly appear alongside Beyoncé herself on the red carpet and on stage; just as they seem to have emerged into the world with a fully developed sound, their fashion choices, too, are preternaturally on point. Their paired Rodarte looks at the MTV Video Music Awards come to mind — and now that New York Fashion Week is in full swing, they're back at it again in Kenzo. The sisters performed at the Cartier flagship reopening party earlier in the week, coordinating — but not matching — before a crowd that included Katie Holmes, Rooney Mara, and Ruth Negga.

Who: Chloe and Halle Bailey, alias Chloe x Halle.

When: Wednesday, September 7.

Where: The opening celebration for the newly renovated Cartier mansion-slash-flagship on Fifth Avenue in New York, New York.

What: On Chloe, a tiger-striped jacquard dress from Kenzo's Fall 2016 collection; on Halle, a tiger-striped jacquard double-breasted coat from the same collection; and on both girls, dandelion-printed tops, also by Kenzo.

Why: Kenzo is a rare presence on the step-and-repeat, and with good reason: Like Rodarte (a far more frequent choice for celebrities on the red carpet), the competing patterns and textures are tough to pull off. But if anyone can, it's sisters Chloe and Halle. Designers Carol Lim and Humberto Leon could certainly do worse for celebrity fans than the Bailey sisters. Their Cartier party looks are matchy, but not too matchy — they both power clash in tiger stripes and dandelions, with almond-shaped kitten heels and teetering, twisted up-dos. But they also demonstrate the breadth of the Kenzo fall collection, which combined school girl charm with tough animal prints and patent leather. Plus, beauty-wise, they go neutral, allowing the looks to speak for themselves — and they're positively radiant.
