Thanks for the info ladies, and Irulan, thanks for clearing that up. I was thinking it must be like the nightie, but that doesn't sound very comfortable to me, or very aero.

Caligurl... I agree. I just want something that will show up on the road so cars don't hit me. I don't need all those flowers and stuff. I'm thankful that I can wear Blaine's jerseys from his racing days, but a lot of them have elastic at the waist, too. They are pretty bright, though, so I make do.
