My favorite females are Orcs, Redguards, Khajiit and Bosmer. The two orc options are not attractive. The best looking female Orc I have seen, was lying dead with a Falmer arrow through her chest, in the Dwemer ruins. Shame, she was kinda cute.
Orcs... cute... those are two words I never thought I'd see in the same sentence unless there was a not in there.
Whoever the Breton Alchemist chick is. She's the hottest. Most all the Breton women are actually, though you can only marry the one. Sadly you also have to join the DB to get her... so... I've joined the DB

To bad you can't marry Saadia. Even though she was a dirty traitor.
