I'm surprised that nobody has mentioned Privilege, by Lisa. http://amidprivilege.com/ I don't share her style aesthetic exactly, although there are many elements I like (in particular, her sartorial elegance and restraint appeal me) but she's funny and very, very smart. And she's about a decade older than I am, so it gives me an idea of what to shoot for.
The only other one I read regularly is Already Pretty, by Sally. I like the "love yourself" message, although I've got to say that her tastes in clothing and colour are nearly the polar opposite of mine, and ever since she cut her hair into a style that really doesn't suit her face, or, for that matter, the texture of the hair itself, I've started to doubt her "eye" for design. (Not that I don't like pixie cuts, but you've got to get the right one for your face, and she talks about how much she likes hers, and to my eye it makes her pretty face look long and jaw-heavy). But it's true that she often wears clothes that work for her figure. However, as far as having a good eye and the best style advice out there, no one can compare to Angie! Her specific advice to each person is almost unfailingly dead on the money. She always seems to suggest the right tweak to take an outfit from "not bad" to fabulous.
