I am an hourglass and am on the fuller/curvier end of the spectrum, so I like to have a slightly straighter cut of skinny jeans rather than being super-tapered in the ankle. I've been wearing these DKNY jeans for nearly two and a half years. I know some other YouLookFab members have *not* had good luck with the denim quality of these skinnies, but I think because I bought them a bit small, I didn't notice them stretching out of shape. (Also, I've been wearing the same pair since 2007, so I think the denim has conformed to my shape over time.) I feel comfortable wearing them with boots, heels, or flats.
I also just tried on Banana Republic's classic skinny jeans. The denim is a little thinner and they are definitely more tapered in the ankle than my DKNY jeans, so if I ever bought a pair, I would wear them only for tucking into boots and with longer tunic tops. However, they were *very* comfortable.
Shiny said in another thread that she wears these skinnies, which are also on the skinnier/more tapered side.
