This Mugler Trademark knit polo perfectly captures the optimistic energy of early-2000s fashion. Bold stripes in lilac, orange, turquoise, and chartreuse create an optical effect that subtly contours the body, while the soft collar and fine-gauge knit make it as wearable as it is striking. Lily picked it up while trying to refresh her everyday wardrobe. "She's so cute," she says. "I bought this in an attempt to refresh my work wardrobe." Here's how she'd style it: "I'd wear with white jeans or white shorts, a good sandal, a cute bag, a cute hat, cute sunglasses. It's perfect for a summer lunch."
