Since launching Nomia in 2009, Brooklyn-based designer Yara Flinn has developed a sleek, urban aesthetic. She continued this exploration of unfussy, forward-thinking clothes for Fall ’13, presenting a primarily camel, white, and black collection that combined sporty, boyish charm and soft femininity. “It’s a lot about contrast,” Flinn told Style.com in a preview. “Not just in the fabrics but in textures and positive and negative space. Achieving a perfect balance is what I strive for.”

Her aim for harmonious dichotomy came through in a slick blazer that was slit up the back, a pair of baggy black wool pants with sheer organza calves, and a quilted bomber in a shimmering silver brocade. Subtle details, like the elastic waist on a fluid silk jumpsuit, gave her clothes an everyday ease, and cropped tops and sweaters paired with high-waisted skirts were chock-full of attitude.

There were a few T-shirts, too, each of which was embroidered with a twin-tailed mermaid. The image was inspired by the Met’s sixteenth-century bronze Siren sculpture. Perhaps an unlikely reference for a modern, streetwise line. But according to Flinn, sirens are an integral part of her brand. Nomia is actually a Greek nymph. And Flinn herself is named for a Brazilian mermaid. “I’m fascinated by strong, powerful, and alluring women,” says the designer. Indeed, her wearable and accessible clothes (they range from $125 for a tee to $865 for a cashmere coat) are tailored for a contemporary temptress. We wouldn’t be surprised if a lot of them flock toward her Fall ’13 looks.

Nomia is available at Fivestory, The Webster, Creatures of Comfort, and Assembly New York.
