While I agree all of these girls have beauty, I think some of the definitions of classic/ unconventional aren't quite on the money. Maybe I misunderstood the question, and it's just what we think, but the whole point of classic is precisely that it isn't as subjective as unconventional. Classic features are a symmetrical oval shaped face, tapered jawline, straight nose, high cheek bones, large eyes and full hair. Karlie is absolutely a classic under this. Audrey has become a classic beauty in the sense she has an enduring appeal, but it is her overall elgance, rather than face that give her her timelessness. She has a square jawline, and thick straight brows, as opposed to classically full arched ones. Both are completely lovely to me, but there's a difference between classic as in 'classical' (stems from Roman-Rennaissance perceptions of beauty), and classic as in 'iconic'.
