Karen O of the band Yeah Yeah Yeah’s has always been admired for her outlandish fashion sense and on-stage performance outfits, long before Lady Gaga attempted to steal her forte. But who is behind Karen’s fantastic stage attire? The answer is a husband and wife duo named Jason Grisell and Christian Joy.

Besides Karen O’s many costumes, the team also has a slew of artwork, dresses, t-shirts and scarves.
