NEW YORK — Danskin and its sister label Dance France are two names that are synonymous with authentic bodywear for real dancers, but during market week they showed that they can deliver the trends without going overboard. For instance, there was lots of satiny shine on ribbed bike shorts and mock turtleneck crop tops, pretty natural heathered cottons in drawstring shorts and Henley tops, and delicate lettuce edging on floral crop tops.
