The granddaughter of Grace Kelly’s clothier has been gaining a celebrity following thanks to her modern approach to eveningwear. For spring Katie Ermilio combined ‘30s tennis court inspirations with Old Hollywood glamour to produce a collection that felt ladylike with a hint of sport. There were leanly tailored strapless jumpsuits and sleek cigarette pants that could turn heads just as well as any ball gown. Elsewhere, a windowpane pattern in green and white overtly nodded to the tennis court theme. It was most notable atop a fishtail skirt worn with an off-the-shoulder blouse for what was an entirely fresh approach to black-tie. It’s only a matter of time before these creations are topping Best Dressed lists next awards season.
