Nicole and Michael Colovos had twin boys over the summer, but they had a different baby to show off at their Helmut Lang presentation: a new bag collection. The fresh arrivals—washed and weathered leather envelope clutches, top-handle day bags, and oblong evening sacks on long leather straps—have much in common with the duo's clothes, i.e. they're studiously constructed to appear absolutely effortless. The best part: They don't look like anyone else's wares. As for the Spring collection, the husband-and-wife team's thinking was in line with other designers this week: fresh, airy, and light. Whites, taupes, and nudes for the most part replaced black; natural, organic textures dominated; and the overall silhouette was looser, more relaxed. A great-looking silk crepe jacket with a chiffon lapel, for instance, came unlined, which means it'll be as easy to slouch on as your favorite cardigan, but a heck of a lot more sexy.
