I'm looking for a pair of skinny jeans in a true black, with a good medium rise (about 9"). Preferably only cotton with a few % stretch, I like my denim to have some weight to it and not feel like leggings (like cotton-polyester mixes tend to do). Does anyone have any tips? I feel like I have tried on every pair of jeans in every store that I know of, but it should be said that the selection where I live is not overwhelming.
