I was happy to find this running skirt by lululemon. It has fashion-forward ruching on the side and a wide waistband. The drawstring is wide as well and stays tied without knotting up. I have tried all kinds of running skirts and this is hands down my favorite.
My style is no longer on the site, so while I'm still crying my eyeballs out that I didn't buy another, I may just *have* to buy this one. It is simple in the front, but ruffles in the back make it super cute.
