I work quite close by to WIT and TheFrugality so often spot them out and about.
WIT is actually not as tall as I thought she'd be, I'd say about 5'2 in flats. Was surprised to learn she takes a shoe size 40 though! (I'm 5'5 and a size 37 shoe!)
As for blogs, love Amber's, WIT, TheFrugality, Fash&Chips and ManRepeller.
Cookies and Candies occasionally has some good stuff too. Her outfits are all very similar but she's an investment dresser so often posts some good things that whet the appetite. Ditto Le Catch.
Style Guile I just don't get, it's too safe and prissy for my tastes. (I also don't think she's particularly stylish.) Ditto SusieSoSo and Does my Bum Look 40. The latter is mostly variations on the same thing and a completely different body shape to me so not much use.
I also follow AtlanticPacific mostly because her outfits amuse me on many levels. I was also shocked to learn how young Blair is, I thought she was a good 10 years older!
I find Vogue's 'What I'm Wearing Today' series quite inspirational too.
And another vote for Recipe Rifle too, it's been one of my favourite non-fashion blogs for a quite a while.
