Friday night saw fashion’s best and brightest flock to the MoMA to toast . Most guests in attendance wore pieces from the storied fashion house, but it appears that tous les femmes were also in on the beauty memo calling for effortless French-girl waves (a minor obsession of ours here at Style.com). Ashley Olsen kept to her signature look, wearing her long blond strands with a classic center part. British actress Mia Goth rocked the no-fuss style, as did her Nymphomaniac costar—and face of the Fall ’14 LV campaign—Charlotte Gainsbourg. Perennial cool girl Chloë Sevigny and model mogul Miranda Kerr also arrived sporting dressed-down curls. To replicate this texture that appears to work for everyone (and never seems to get old), we suggest turning to the purveyor of Parisian beauty herself, Caroline de Maigret, for advice: Ditch conditioner (it makes hair “too sleek”) and your blow-dryer. Stifling New York City studios have to be good for something.
