Rich burgundies, Yves Klein blues, and saffron yellows were among the deep hues Calvin Klein used in his Spring 1997 collection, presented at the Dia Center for the Arts. Models were alternately shod in laced men’s-style oxfords, flip-flops, and strappy high-heeled sandals, which hinted at the variety of looks and attitudes in the lineup. The strongest pieces were the draped and asymmetric ones. In one silver-slashed strapless number, Vogue wrote that Klein was adding “an Eastern flavor to his minimalist ethic.”
