Extra long leg warmers?

Has anyone bought extra long leg warmers? I am looking to get some that cover my ankle and go up to the edge of booty shorts. I see a lot of them that look like they slouch easily and was wondering if anyone knows what to look for in warmers that would not slouch as much, something nice and thick, so it stays up a bit better.  Any other advice on your favorite extra long leg warmers, slouchy or otherwise, would be much appreciated too :)
