About the worst thing you can do for your visibility is wear clothing that breaks up your body shape into unrecognisable fragments, such as team kit. This is the essence of camouflage and is the last thing we need to be doing to ourselves. A hi vis tabard, as worn by road workers, is good partly because the stripes of reflective material are instantly recognisable to any motorist who's ever seen a road worker wearing one and partly because the reflective material maintains your body shape. But if you haven't got a hi vis vest, wearing a solid block of colour is almost as good, at least in daylight. What we do about motorists driving at us because they've fixed us in their sights however, I don't know.
