Urban Outfitters Silence & Noise Carnation Zip Skirt
This skirt is a bit short for my standards, so I got one a size larger than what I usually wear. But it does have pockets! Very useful for Cons. Also, though the label says Silence & Noise, it was originally marketed as Sparkle & Fade, so it's worth eBaying under both.

Karen Millen Masculine Oversize Check Skirt
This has become an expensive item on eBay. I have no comments on fit. I find it true-to-size. If you're looking for a cheap alt, search eBay under "plaid wrap skirt." I saw lots of good options, though a lot of them would need to be hemmed shorter. There's only one tiny pocket, good for a few bills and a credit card, but not much else.

Topshop Black Leather Tall A-Line Skirt
Remember: the tall variation is SA, as it is the only one whose lines match up correctly.

Topshop Folk Jacquard A-Line Skirt
There were quite a few of these left when the ID came out, so hopefully a lot of cosplayers got them. There was also a slightly more expensive version, identical in every way except that it had beadwork. It was called the folk embellished jacquard a-line skirt. That may actually turn out to be the SA skirt, but only time (and better screen shots) will tell.
