I actually planned to make two denim skirts from the start, just one a bit "fancier" than the other. I drafted my own pattern from an existing denim skirt that I own - I've actually used this skirt as a pattern previously for a couple of other skirts, so this time I made up some proper pattern pieces so that it makes it a lot easier in the future.
This skirt is just a simple A-line skirt, with a zipper fastening at the back, but I love it and can wear it with so much. The only problem that I discovered afterwards is that it's really bad for static - it clings and bunches something shocking if I'm wearing tights or leggings underneath - so I really should have lined it.
I did learn from my previous skirt though, and lined the border with anti-static lining - success! No bunching or clinginess from this skirt, so I think this will be my winter denim skirt that I wear with thick tights/leggings and boots. And in Melbourne, that usually becomes my staple outfit for at least 6 months of the year.
