We love Miley Cyrus for her eclectic and ever-changing style, but she took the opportunity this month to highlight sustainability by posting a photo on Instagram of herself in a vintage store mirror. The caption read: “Tom Ford but make it thrifty. Previously loved/owned clothes = most sustainable fashion source.” And, she’s absolutely right. Regardless of your feelings on exotics, leathers, furs, and more, Miley’s notion of shopping from the world’s already-existing merchandise easily cuts out any byproducts and downsides to production. But Miley is not the only celebrity who loves to shop vintage or steal from the wardrobes of chic parents and grandparents in the hopes of repurposing fashions of decades past. Ahead, find some of our favorite celebrity vintage moments. Because, if you’re going to go retro, what better way than through the OG trends, as they were created way back when?
