J.J. Martin is a Los Angeles–born editor turned entrepreneur and founder of the hugely successful Milanese lifestyle brand La DoubleJ—now a global phenomenon. Having spent years scoping out the very best of Italian fashion and design as a contributing editor for publications including Harper’s Bazaar and Wallpaper*, Martin launched La DoubleJ in 2015 as a shoppable magazine selling vintage clothing and jewelry. The brand soon expanded into a full lifestyle label offering new fashion made with archival prints, cool home design, and rare vintage—all distilled through a lens of pure joy and eye-popping print—and championing Italian talent. With collections sold in more than 200 stores worldwide, La DoubleJ’s first flagship store opened in Milan’s high-end fashion district in 2021, complete with a dedicated floor offering a spiritual haven for shoppers and venue for female empowerment workshops. Martin lives in Milan.
