Like Coco Chanel once said, "In order to be irreplaceable one must always be different." And Billie is definitely irreplaceable.
Of course, Billie's lace gloves were also Chanel. Just a casual fashion flex. And we love the slightly smeared look of the iconic Chanel logo on her jacket.
Because we always need a good close-up of her signature hair and the unexpected colorful hair tie (more on that later).
And can't forget about the bling, with the teen rocking Chanel earrings and some serious rocks on her fingers.
Leave it to Billie to make Chanel look and feel as comfortable as athleisure.
We're so glad Billie didn't listen to the old fashion rule of "before you leave the house, look in the mirror and take one thing off" because her accessories are sick.
Big brother Finneas O'Connell looked dapper in a Gucci suit.
And that's a wrap.
