Other designers may be embracing color, clashing prints, and embellishments, but minimalism isn't a passing fancy for Calvin Klein Francisco Costa. As is his habit, he stuck steadfastly to a monochrome palette at this morning's Resort presentation, showing dresses and skirtsuits in black, white, navy, or icy gray. The silhouette was body-conscious but not clingy; waists were clasped with micro-thin belts, and hems grazed the upper shins. Models wore white-soled sandal flatforms.
