Amy Winehouse became a modern-day style icon shortly after bursting onto the scene in 2003, with a little help from her signature beehive; heavy winged eyeliner; skin-tight, thigh-skimming dresses and skirts; and, of course, her rockabilly forebears. In fact, until her death, seven years ago, on July 23, 2011, Amy Winehouse was so committed to her signature style that she was rarely pictured in anything else. (For a court appearance in 2009, for example, she was pictured in the surprising combination of a tight tailored suit and pearls—hair and makeup intact.) When it came to maintaining that status, she didn’t shy from shortcuts; while on tour in 2007, Winehouse once saved packing space by wearing one of her go-to ensembles—short shorts and a white tank top—while performing at both the Isle of Wight festival and Coachella. Sometimes, she studded those staples with embellishments; over the years, everything from real roses in her hair to a bottle of wine and a tabloid served as her accessories. In honor of the late singer, take a look at some of her most pioneering looks—plus a snapshot of her blonde streak matching the manes of Mary-Kate and Ashley Olsen—here.
