It is rumored that the F3 are all women and that 2 of them are blondes. So we "know" Irena makes it. The other two are either Carol H., Althea, or Gordana. While Gordana isn't a complete blonde like the others, one might categorize her that way. So....the real contest is between those 3, I think.
Also, I guest Christian Siriano saw the F3 runway and wasn't very impressed with any of them. He said the winner has some good stuff but that much could be tossed (paraphrasing). So, we'll have a lack-luster finale to complete the rather lackluster season,
