Sam Shipley and Jeff Halmos quoted Ayn Rand in their show invitation, and the mother of objectivism would surely have been impressed with the resolutely modern collection the duo created for fall — a darker, sleeker vision for the brand than seasons past. Models zigzagged through slender columns of an industrial loft space, carefully tracing a painted white line on the floor. The men were sheathed in slim black turtlenecks with sleeves that ended in fingerless gloves, over which they wore crisply tailored suits — some in shimmery silk fabrics — or abbreviated peacoats. Women (see images) donned black bodysuits, layered beneath well-cut, structured dresses in wool or satin, many accented with zippers or TV-static prints. Jewelry by Philip Crangi and futuristic eyewear by Mykita finished off the precisely styled looks. “It’s a study in the aesthetics of self-empowered, determined individuals,” said Halmos. “They walk the line and never veer.”
