The fabric I used for these skirts is super cool. It's kind of finicky to sew sometimes because it sticks to itself and other smooth surfaces, but it moves so well as a circle skirt. If I could afford it I would have gotten every possible color, but I settled on these two.
It's a very simple pattern - just a circle and waistband (surprise, surprise). There's no zipper or elastic because the fabric is a strong enough spandex to support itself.
As you can see on the inside, there's really just a waist seam and one connecting the ends of the waistband together. I zigzagged the waistband on to preserve the fabric's stretch.
PS. This skirt along with many of the other items I've been posting lately are available in my shop.
