Lyn Devon has steadily carved out her niche in beautifully made clothes with an all-American upscale aesthetic. Her business is still small, banked for the most part on private clients, but retailers are taking notice — Neiman Marcus was one of her first appointments on the day of her presentation. For fall, Devon’s collection was as well-rounded and well-crafted as ever — gorgeous, top-notch fabrics galore in rich cashmeres, wool jersey and suede — with a push toward sportier, less ladylike fare than usual. Also new: jewel tones and lively patterns. She said her seasonal muse was a global traveler who favors “polished classics mixed with something quirky that she’s picked up.” So there were chunky knits done in checkered stitches and paisley pajama pants. The silhouette was longer and leaner with great coats, such as a royal blue cashmere trench, and slim jersey gowns with bustier tops — conservative with a subtle edge. Everything was finished impeccably — from the colorful silk linings to the shift dress tied with a magenta cord at the neck.
