Yeohlee Teng is an avowed conservationist, so sustainability is key to her work ethos. "We recycle our paper, we pick up our pins," the designer said at today's low-key presentation in her Garment District store. In keeping with that spirit, Spring's clothes were made, in part, from vintage stock and fabric ends. For Teng, a practice like that is just common sense. There was a logical bent to her designs, too. The last dress out, a linen trapeze with three tiers of white silk satin organdy flags acting as an overlay, was based on a mathematical equation. The width of the rectangles led to the dimension of the yoke, which…well, we're sure the math adds up.

Although math and geometries were inspirational here—Andrew Geller's double-diamond Pearlroth House in the Hamptons was another reference point—the clothes were light and airy. They floated away from the body and looked, as Teng intended, like pieces that would last.
