What The Hell Kind Of GD Outfit Is This?

Is her royal alien highness, RiRi, auditioning for "Chicago" or something? This outfit only belongs in 2 places: a Broadway stage and an "I Love Lucy" episode. There was this hot ass outfit that Lucy always wore on the show. It looked just like this, but Lucy wore a chiffon dress over that crap. I really think RiRi used her alien powers to break into the Lucy archive closet and snatch this number out.

Here's RiRi at an InStyle Magazine party last night in Hollywood.
