In summer I wear brightly coloured tops, but for winter use I have a black softshell jacket and a grey one. Nothing to do with fashion, but light colours would all turn grey quite fast with road splash anyway, and washing jackets often isn't good for the water repellency. Mainly it's because winter riding here = riding in the dark, and in the dark there's no difference between black, red, fuschia or turquoise. Lights and reflective stripes are the way to go, and I'm decked out like a Christmas tree. In daylight bright colours are easier to see, but then again - in a busy city environment there's colour everywhere, so even then it's the flashing lights that announce to everyone "cyclist ahead!".
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
