"I've been using neons as neutrals for the last 25 years," Isaac Mizrahi said at his Resort presentation. True enough, but the designer seemed even more obsessed with vivid colors than usual this season. "It just feels right," he added. A nude twinset paired with a fluorescent lemon yellow skirt had editors calling dibs, as did a long, belted muumuu in a psychedelic candy print. It wasn't all electric brights, though. A black and white polka-dot belted pajama suit and a one-shoulder long dress in a microdot looked a shade more restrained, but no less fun.
