Personally I don't find ANY of the companions very classically attractive.
But as a hetero-female the two characters I find the most physically attractive are Cassandra and Vivienne.
Personality-wise, so far Cassandra (I like her hard exterior and soft creamy romantic center) and Cullen (steadfast and awkward).
(And Varric.....That chest hair!)
But then IRL I am a non-feminine female.
No make-up, no dresses, no high heels. Don't give a fig about shopping or fashion. Don't even wear jewelry. I know how to use power tools, have framed and wired houses! Am a geologist who when I work in the field, my work outfit consists of FRs a hardhat and steel toed boots.
And through it all, no matter how un-typically-feminine I may be, I have never lacked for dates.
So reading through the thread, what I'm getting from the OP is that he wants the 'ultra feminine media scrubbed clean' type of girl. He's bought into the media image of women always being made up and pretty.....even MMA fighters with their make-up and hair, don't end a match looking like they went into it....no matter what Hollywood says....women don't wake up in full make-up with perfectly coiffed hair.
And the reason women like to take on more 'masuline' attributes is because those attributes are usually seen as being 'competent'. Why wouldn't we want to feel empowered by taking on 'masculine' rolls when it is the masculine that is upheld as the powerful, the meaningful, and the worthy? A man is labeled as opinionated or strong, when a woman does it is she's being bitchy....even if they say the same thing in the same tone of voice.
