I like her because she has a genuine, fun personality... she's really fresh and doesn't take herself too seriously. I find most models uninteresting and uninspiring (Gisele and that whole look for example, or Vlada types...), but I immediately fell in love with Agyness the first season she appeared. Her looks, style, and taste (the whole British punk and androgyny thing) are quite refreshing, a spark much needed in the industry. I like that she has a simple, charming face without severe features-- she's not a conventional beauty, but a beauty nonetheless! Plus she can take amazing photographs; she is very versatile as someone has said. Meisel doesn't choose run-of-the-mill girls as his favorites!
I guess it also helps that we both share cropped hair and the tomboyish aesthetic

.... Sort of rooting for the underdog I suppose (now that I think of it, most of the models I DO like are a bit unusual...). But I could understand how some people wouldn't like her. It's all a matter of taste, and whenever a model has a strong look like Agyness, there is always division....
Anyway, in this video some fashion people express why they like her:

On another note, I wish she would get her hair trimmed!
Here's a myspace bulletin posted by The Facehunter:
Blah!
If the Face Hunter Awards would exist,
without a doubt,
Agyness Dean would easily be nominated.
