I tested a pattern (and discovered the wonder that is Undersummers) and so now I have two skirts. The patch pockets were my own addition. Because you have to have pockets.
This one is a little below the knee. The elastic waist is really too loose, but I'm too lazy to fix it.
This one is about calf-length. The original pattern is about ankle-length, and I still might shorten this, as it's really hot this summer.
