How to wear ultra-short? It's the brainteaser of spring fashion. For his Lagerfeld Gallery collection, Karl Lagerfeld gave shorts themselves a try. As part of the Diesel jeans group he integrates into the collection, Lagerfeld put frayed-edge denim shorts beneath minute chiffon dresses and under the teeny veils he had flipping around in place of evening skirts.

The jeans, with their signature center-front seam, sculpt the skinniest thigh on the planet. For spring, they're done in pale blue, cross-dyed purple and blue, faded black, or white, and lopped off just below the calf. Lagerfeld often put them under pretty lavender chiffon dresses for a more covered-up option.

For all the denim, this wasn't a casual collection. There was a Lagerfeldian framework that included formal jackets and crisp white shirt collars alongside feminine silk dresses. He did a few twists on the tux, including black taffeta-sleeved evening coats, cropped boleros and a white-tie vest. A line-up of pewter ciré swimsuits with boy-cut legs touched on the '60s trend. And the famously slimmed-down designer rivaled any model when he took his final bow in a pair of those long, leggy jeans.
