Move over, Marsala. The shade’s sweeter sisters—red, pink, and particularly purple—have stepped into the spotlight. In the fall collections, Anna Sui presented plenty of plum in her rich-hippie designs, and Erdem showed shimmery magenta jacquards. Meanwhile, Beyoncé just covered September’s Vogue in a lacy lilac Marc Jacobs creation. Fortunately, there’s no lack of crossover with jewelry: Amethysts, tanzanites, rubellites, and other gems are all contributing to autumn’s purple reign. 1.
