Rational sizing for women's pants

Why are men's pants measured in inches, but women's pants in "sizes"? We're not sure, but we're pretty sure that it doesn't make much sense for the people trying to buy pants. And we want to fix it.

We intend to build a database of measurements allowing women of all body types to find jeans that fit without spending hours in a dressing room. We need help deciding what to call our endeavour! These are some possibilities:

  1. PantsData (pantsdata.com)
    Slogans: "The Internet Pants Database" or "Pre-game for the fitting room"
  2. Human Jean Project (humanjeanproject.com)
    Slogan: "Jeans that fit humans"
  3. DataAss (dataass.com)
    Not sure that it needs a slogan.

We are open to other suggestions as well. Let us know!
