Marni is an Italian luxury fashion label founded by Consuelo Castiglioni in 1994. Castiglioni was the label's designer from 1994 to 2017. The current designer is Francesco Risso, who had previously worked at Prada.

Today, the company produces ready-to-wear clothing, handbags, jewelry, and eyewear. Jenna Lyons, senior vice president of women's design for J.Crew, attributes Marni's success to the "post-Tom Ford era," saying that women are lately being bold through color, print, and shape rather than through overt sex appeal and are dressing more for other women than for men.Marni launched its first menswear line in Fall 2007, introducing leggings as standalone bottoms for men.
