I wear running skirts sometimes, but have been more into wearing shorts as the summer went on. At first when it's warm, the shorts just seem sooooo very tiny after having been more bundled up and encased in spandex all winter. Then once it gets hot, I only care about function and no longer have any issue with whatever that looks like.
I do wear a skirt if I'm out and going to run errands or to grab coffee post-run. The booty shorts I wore for a run look sort of out of context sitting in a local coffee shop, in a chi-chi downtown area, having breakfast with a friend after. Doh!
Ruffles are not my thing, though.
