A Fifties breeze blew through Peter Copping’s cruise collection for Nina Ricci — the look, an ode to vintage couture-chic with a few unexpected twists. Swimsuit details inspired the back of a languid red evening dress, and the micro minis, styled like a retro bathing suit with a cotton ribbed cardigan. They came mixed and matched in a graphic, pink-and-black flower print, loosely inspired by a Provencal theme, a small-scale version of which appeared on a ruched pencil skirt paired with a khaki blouse. As always at Nina Ricci, the focus was on a certain airiness and delicate details worked in light yet textured fabrics. For example, the tweedlike effect on a purple silk dress with a sheer bustier bodice and matching cropped jacket. Pointy pumps with Plexiglas heels and cat’s-eyes sunglasses added to the whole retro vibe.
