Made my bi-weekly trip to Costco this morning, and spied Ellen Tracy ponte knit pencil skirts for $16-something. I didn't buy one (yet), but the quality of the item looked very good, and this would be an extremely useful item to have for fall. At $16-something? You can't possibly lose.
The skirt looked like a 'seamed' pencil skirt of sorts - nice material - but not lined. Still though, at around $16...you can't beat this price and quality.
editing to add: the only colour available was black.
