The kids are in couture and the grown-ups are in oversize bows. When did things get so Freaky Friday?

For Christmas last year Nicky Rothschild’s eldest daughter, Lily-Grace, who is seven, asked for two things: a jean jacket and a jump rope. Which seems like a normal request for a child her age, right? Not anymore. These days kids are more precocious than ever, and nowhere is this more apparent than in their shopping habits. Ten-year-olds are emptying the Drunk Elephant shelves at Sephora. Eightyear-olds are walking into boutiques in Beverly Hills and asking for Off-White crop tops and Stone Island bombers.

The conditioning begins early. Take Sienna Miller. Days after giving birth to a baby girl, she went for a stroll around London with her newborn swaddled in an Artipoppe carrier made of vicuña and cashmere that retails for $3,800. Then, of course, there is Cardi B’s five-year-old, Kulture, reigning princess of Instagram’s rich kids. (She has her own account, @kulturekiari, with 2 million followers.) Kulture has been carrying around a pink Birkin—not to mention mini It bags by Balenciaga, Gucci, Louis Vuitton, Chanel, and Dior—since she was about two.
