I don't wholly admire any famous person perhaps mostly because I don't know any personally, but I do make use of them in a "role model" way. When I first started trying to understand women's fashion it occurred to me that wealthy celebrities just hire expensive stylists to choose their clothes, hairstyles and makeup fashions. So why not pick a celeb or two whose look I like and adapt their style to an extent?
That's what I've done and I regularly check the fashion pages for my celeb role models' latest street looks. I save pics to a folder on my computer and refer to that before I shop for clothes. I don't buy the designer labels they're wearing, but I find it's easy enough to find low cost alternatives to most designer fashions if you search a bit.
I don't say which celebs I follow, though, so as to not be seen as a second rate version of someone else. Ha! Actually, when you do this you always end up creating your own look, just using the celeb style as a starting point.
