So here is my solution - light knitwear. A cream hat or scarf would help make me more visible I'm sure. I have played with the thought of sewing a small reflective strip onto my bag and might still do that, but seeing as I need a new woolly hat anyway (I left mine on the bus last winter) I think I might as well buy a light coloured one.

(PS I might well be far too old to rock mittens with pompoms but these ones are so warm and snuggly that I'm not sure I'll be able to resist.)
