If you've ever had the opportunity to attend an art fair or, perhaps, click through a slideshow of photos from one (or any number of parties), you're likely to have come across a striking pair of bald women wearing hyperfeminine frocks and technicolor makeup. They're EVA & ADELE, Berlin-based artists and partners in life and work. For over two decades, they've dressed the same way, eaten the same things and alleged to have never spent a night apart. Their hermaphroditic appearance is not superficial -- though technically born male (EVA) and female (ADELE), neither identifies with either gender, instead having told a reporter that they've "invented our own sex." EVA even recently had her sex legally changed to female on her birth certificate despite not undergoing sex reassignment surgery, following a 2011 constitutional ruling in Germany that permits transsexuals to change their sex even if they don't change their bodies. The two married that same year as women.

Along with their day-to-day "life as art" performance, the duo also create self-portrait paintings, installations, books and polaroids from their studio in Berlin's posh Charlottenburg area. We sent our photographer Rebecca Smeyne to shoot their studio and adjoining home, where they showed us everything from their "costume plan book" (they often map out their coordinated outfits weeks in advance) to their rows upon rows of matching pink shoes and gave us an inside peek at the lives of two art world originals.
