This brand’s designer, who goes by the name Olga, staged her spring show in a tiny art gallery, with audience members seated in overstuffed sofas and armchairs. Models stopped at intervals on the runway to illuminate their clothes with black lights, which were carried with them or hung from the ceiling. The collection was made up of loose t-shirts worn as minidresses, oversized tuxedo blazers with contrasting black lapels and cuffs, tissue-fine jersey pieces slashed in places to reveal skin, and pleated pants with extra volume around the hips. The palette consisted of soft and delicate shades of pink, gray and blue, offset by black and rust. Abstract prints, one geometric and one watercolor-like, showed up on both men’s and women’s pieces.
