Asa Soltan is one of Bravo's more intellectual stars, so it shouldn't come as a surprise that she dressed up as revered artist Frida Kahlo.
Mercedes "MJ" Javid, meanwhile, went meta with her Halloween costume: her cat get-up is a perfect send-up of the one Kim Kardashian wore a few years ago. And she donned it for her appearance on Access Hollywood today, where hosts Kit Hoover and Billy Bush dressed up as Kris and Bruce Jenner.
