What, exactly, is the algorithm the contestants of RuPaul’s Drag Race use when choosing their premiere outfits? Some of them swan in looking like slightly outdated divas in sequins and heavy eye makeup, and some nail their flags to the mast. Take Sharon Needles last night. She doesn’t walk in like this is a job interview and she wants to make a good impression; she skitters in unevenly in character, zombie contacts screwed in, witch’s hat planted firmly on her head. Rev your engines, bitches, because this… is RuPaul’s Drag Race Season 4.
