I call this skirt the "modesty trainer." This is because it is so tight it forces small, ladylike steps and controls how one sits. I bought it to go with undergrad university t-shirts, which are red.
This is another one from myculottes.com. It is exactly the same as the long denim, the long brown, the multicolored floral, and the long pink; except that it is kid-sized, not adult-sized. It therefore hangs roughly to my mid calf, and is snug. I mended part of one of its side seams myself, by hand.
And this one is the "not quite denim!" I call it that because it looks denim, but is actually soft cotton. I added the purple patch myself to cover a hole I made when I fell rollerblading.
