Despite Michael's creepiness, Lee's coarseness, Helene's two-facedness (and a personality and opinion that change like the wind) and Claire's all-around dislikeability, I still have to say Raef because, like Michael, he is creepy and, like Helene, he is two-faced, he's just the opposite of Lee (which makes him even worse) and he is too scheming to be too open in any way that may expose his true self (ie no more likeable than Claire). Added to which this week's task proved that he's not much of a salesman and scared people off rather than attracted them to the stall (the only dresses the team sold were sold by Claire).
For all that and for being the most overrated and most inexplicably popular contestant, my vote goes to Raef.
