Aesthetic perfection is contestable; each person assesses it using different yardsticks. I find Angelina Jolie very interesting to look at. She isn't 'perfectly' beautiful, but her face has an overwhelming mystique and raw, almost macsuline femininity, which I find very uncommon and very arresting. She represents the subjective variety of beauty which hinges on each person's personal definition and taste. Though whether she is truly 'beautiful' ( I personally think she is, in an unconventional, elusive, defiant and contradictory way) or not is debatable, that she is overwhelmingly arresting is not.

But by the same token, I don't find Megan Fox to be beautiful.
On the other end of the spectrum, there's the brand of beauty which doesn't have to be 'judged', but is something factual and announces itself thus at first glance. A face so truly, classically and timelessly beautiful face that it doesn't need to be studied or analysed or got familiarised with to be deemed beautiful. Natalia Vodianova instantly comes to mind. But some find this brand of 'obvious' beauty to be boring, and I can see where they're coming from. There's absolutely nothing left to interpretation. Some people like to make their own choices and come to their own decision, rather than be
told something is true. Nevertheless, I do think Natalia is indeed one of the most beautiful models of all time. We have to see how she ages.

Gemma Ward, is and will always be an extremely
pretty girl. However, I don't think she'd ever be an extremely
beautiful woman. There's a certain immutable fragility and 'child-like' quality about her face, her features are impeccable and lovely to look at, but when juxtaposed together I think she lacks that singularity which typifies beautiful women. She, however, did parlay her alien looks into editorials and campaigns galore. There are models and actresses whom I find very pretty but not essentially beautiful - Amanda Seyfried, Rachel McAdams, Vlada, Barbara Palvin, Toni Garrn, Lily Donaldson, Lisa Cant, Heather Marks et al.
And then there are women whom I don't find even pretty, let alone beautiful or perfect. Cheryl Cole, Blake Lively, Megan Fox, the Twilight cast and basically a lot of young actors whom magazines and those horrific 'Most Beautiful People Alive' lists ram down my throat as
beautiful.
