Now that's a far more difficult call than the last one.
Typically, Cordelia is more my "type" but Willow is a special cross between cute and hot that...does things for me.
My "it girl" growing up was Alyssa Milano, and I have a real weakness for brunettes as a rule...but then there's girls like Juno Temple or Emma Stone that really get their own category.
In this case, I'm going to have to go with Alison Hannigan, but in the other topic where it was Dushku vs SMG... Dushku wins hands down until someone mentioned Charisma Carpenter...then it's a coin toss.
Truth be told, there's very few blondes that do it for me. JenLaw, Emily Kinney, Iliza Schlesinger, Kaley Cuoco, and Katheryn Winnick make up the shortlist of blondes off the top of my head that make up my top 50 list.
By and large, over half of my list are brunettes, and there comes a certain point where any ranking order becomes meaningless in the top half of them.
It's also a real shame that Olivia Munn ruined herself with plastic surgery...
