Moments before Erin Fetherston was to show her collection, a model decided she was uncomfortable wearing just a sheer top. "We had to come up with a wardrobe adjustment," said the designer, who solved the problem with a camisole. Another model braved the flashbulbs in a gauzy blouse, and while nipples are okay on Fetherston's runway, butt cheeks aren't welcome. "I hate that," Fetherston said of the burgeoning no-pants trend. "I really believe in people not forgetting their pants."
