For my commute, I just wear whatever I plan to wear at the office, which often means skirts and dresses. With a step-through frame this is no problem at all. I do get lots of comments, but they tend to be the "hey, that's really cool" variety. I also get lots of double takes on the road, and it seems like maybe motorists give me a little more space when passing. There's something about a woman in a dress on a bright red bike wearing a high-vis saftey vest that makes people think my bike handling skills might not be great! I'm okay with that perception because it works in my favor
