There are some who use Instagram simply to show off their latest finds, and we heartily cheer that stylistic voyeurism. And then there’s Cambridge resident Shendi Xu. The 24-year-old, who does Web-based editorial work for MIT, uses the power of Instagram to make sure she’s using every garment in her closet.

“The Instagram challenge is not to repeat usage of any central item of clothing until I’ve worn everything,” she tells us. To do this, she photographs herself in an ensemble every day, creating a fashion diary for the world to see. It’s just the latest step in what she refers to as her “stylistic saga.”
