You're not dreaming, but the Golden Fleece might be hard to find. I find that most soft shells don't have enough windproofness to use as cycling jackets. They are great when the wind is up to 15 mph, but add on the speed of a bike and you can get chilled pretty quickly. The ones that are heavy enough to block out all the wind are often too insulated, and on the warmer days can be sweaty.

Thankfully, there are some good jackets out there made with Gore Windstopper [or the equivalent] that insulate enough, breathe enough and totally cut the wind. I really like my Craft WS Thermal jacket for these reasons. As far as fashion goes, it's in the eye of the beholder. Rapha makes a very attractive shell jacket, but it's flagrantly expensive. My Craft is fairly understated for a cycling jacket, but it's not going to work well with a tie and slacks.
