In the last 2 years, I have made several dozen of said skirts. I've made most of them in scuba or knit type fabric because they are so easy to make and comfortable to wear. Scuba (like bathing suit material) travels well and is surprisingly not hot in the summer. It wicks moisture, never wrinkles, and looks great. Also, if you have a steady hand, you don't have to hem this fabric. I've used my rotary blade to make an even cut.
I added a flounce to this skirt just above the knee. It also has a very comfortable yoga waist. Another alternative is that it can be simply sewn with elastic at the waist. There are many tutorials out there but here are several that are easy to follow:
Note the hem is unfinished.

Note the yoga waist band - easy and comfy.
The flounce begins just above my knees -
good for walking, running, jumping for joy.
