Black tights

Every day on my cycling commute I have a section of path which is co-shared with one Sydney’s best-known running paths.

Over the last 6 months I have noticed something very strange; the female running/jogging/walking population on the path have almost universally migrated to black three-quarter tights, away from a motley collection of short, tights, skirts, you name it.

The two things that puzzle me are:

1. How did they all decide, in such a short period, to adopt the same uniform?, and

2. How did over half of them get conned into this given that it’s not doing them any favours at all?
