Honestly I have no idea. Before this year I saw nothing but roadies, and probably didn't see 10 other riders all year. This year I'm seeing other cyclists nearly daily, but I don't really pay any attention to what they're wearing.
As soon as the population of hot chicks riding just in front of me that I can possibly keep up with (there goes my heart rate) increases (to at least one), I'll let you know what they're wearing.
