Anna Dello Russo, the Italian style icon perennially adorned to the hilt, has never encountered a sparkling bag or bauble that she didn’t like. Her collection of extraordinary accessories is so vast that she keeps a separate apartment in Milan just for storage in. “I am like a guardian of fashion,” she explains. “I collect it as if it’s my job.” Dello Russo has translated this unabashed taste for excess into a wonderfully over-the-top accessories line for H&M, debuting next month. Among the fanciful offerings: a green feathered headpiece, traffic-stopping thigh-high stiletto boots, cat’s-eye sunglasses with bedazzled alligators on the brow, and a baroque gold- and-turquoise trolley in which to carry it all. “Every piece has to be fun—otherwise why would someone buy it?” she says. To better understand her creative process, we asked Dello Russo to walk us through some of the sensational loot.
