Founded in Paris in 1945 by Céline Vipiana, Céline evolved from a made-to-measure children’s shoe business into one of France’s most influential luxury houses. Its modern identity was transformed under Phoebe Philo, whose decade-long tenure made the label synonymous with intelligent, understated womenswear. Hedi Slimane took the helm in 2018, introducing a younger, sharper sensibility and expanding the house’s vocabulary to include graphic knits and a more overtly playful take on branding—of which this “Refresh Yourself” sweater is a particularly charming example.
