Would I look or seem fake if I....?

I want longer extenions. Possibly 24 or 26 inch. I want to dye my hair brown with a chuck of carmel hair dyed under neath on each side. Also I want fake eye lashes because I think they look really good on the TV girls. Also it makes your eyes stand out more. I just want to look prettier and hotter. I just think if theres ways to look as best way you can and make yourself look better and feel better you should do it. Im 14 by the way. So if I wore make up, fake eyelashes, and extenions would I look fake? Also I want to dress like this: http:// www.polyvore.com/new_natalie/ collection?id=789312 I know my parents would let me do this cuz I never got into any trouble and im the good girl type also im going to be in highschool soon so yeah. Thanks :) btw I dont own that polyvore collection thanks :) P.S. I want my extentions to look reall and pretty and natural like the girls on TV. I noticed most celebs wear extentions and still look pretty and not trashy. Or would it still look bad?
