I'm a huuuge Citizen's of Humanity fan. I bought one pair ($200 -- ai. my bank account still hurts when I think about it) three years ago and I STILL wear them everyday. Wicked expensive but totally worth it -- still in perfect comfort, color, and condition!

Other than that there is a pair of Rock and Republic jeans that fit me perfectly (in the store.. can't quite afford them yet and hard to find discount) and my True Religion corduroys take over for my Citizens in terms of everyday wear during the winter.

If you're a jean addict I highly recommend Century 21 in NYC or Nordstrom's Rack in Chicago. I never pay full price for anything :)
