Hang on a minute - this is RETRObike. Most of the comments so far seem to be about current team kit but aren't we here because we ride stuff that may, in some cases, have been state of the art but is now obsolete? So if I ride my Raleigh Team Pro and wear the 'right' top then that seems to be appropriate (only it is acrylic rather than wool).
And, for what it is worth, if I had a modern bike I wouldn't dress up as a pro cos I'd be self conscious about being a slo-mo replica! Where I live I see a wide variety of highly desirable machinery - mostly with a wheezing chubby pilot struggling up the many hills ...
