Purple, with its symbolism of mysticism and utopian ideals, has long been a favorite of hippies. This season that bohemian spirit is still there, but it is refined with flower-petal shades, fluid fabrics and shapes that are soft yet precise. The hue looks particularly fresh worn head-to-toe in jumpsuits or frocks, or used as a surprise color pop — as in a diaphanous dotted swiss maxi-skirt styled with a simple white tee and easy trench.
