I fall into the "love them" camp. I own several running skorts and have run all but one of my marathons in a them. They're comfortable, non-chafing, and damn cute. Plus, unlike wearing shorts in 90% humidity, you don't look like you've just wet your pants after finishing a long run.
Skorts slowly seem to be gaining acceptance in the running community so obviously it's time to introduce something new: the running dress.
Check out these dresses from Nuu-Muu. Super cute. The photos are from the Adventures of Running Mom site. This is a real runner (read: not model) in one of the dresses. I love how it can transition from running dress to outfit with the simple addition of some yoga pants.
Still, I'm not sure I have enough moxy to carry off wearing one of these. But I felt the same way the first time I showed up in a skort, and I don't even blink now about pulling those on. So yes, I think a running dress is in my near future, along with some Girl Shortie pants to wear beneath it.
