On any given Saturday in Los Angeles, toddlers — and their parents — are ready for their fit check. At the Arroyo Park playground in South Pasadena, a tiny Justin Bieber, clocking in at 32 inches tall, is dressed in an oversize red sweatshirt and baggy blue jeans with a pair of neon Crocs. Across town at the Playa Vista Farmers’ Market, a Billie Eilish look-alike, wearing a roomy hand-drawn graphic tee and clashing track shorts, is scarfing down a carton of raspberries. Meanwhile, at the Grove, kids are practically tripping over their baby-size JNCOs as they rush to hop on the trolley. Some days when I’m out with my own 3-year-old, I take style notes in my head. Perhaps when my kid is over his Spidey-merch-only phase, he too can wear a loose-fitting, swirly-print sweater with billowing striped pants.
