Derek Lam  made his Fashion Week debut in 2003, sending out a collection that would mark a new era  in crisp, clean, American sportswear. He redefined the classics, crafting a cool line of looks that felt utterly modern thanks to smart tailoring and attention to detail. What remains in each reincarnation is an unmistakably chic aesthetic — effortless, easy, and wearable. He loves color as much as he loves black; he experiments as much with the classics as he does with edgier designs and prints but continues to deliver a clever mix of the slick and the feminine.

Layering was big, with boxy crop tops worn over dresses. And texture had its moment to shine, such as this roughly woven dress you want to reach out and touch.
