Flat caps.

[Vapin' Joe]

I keep one on the rear parcel shelf of my car. Following drivers drop back when they see it.

I wore one during November and December of 1986.

Dexy's or Chas and Dave - not sure which!

I wear a flat cap occasionally - black and white herringbone, cost £10 from Top Man - most of the high street fashion shops are selling men's flat caps in various forms. Not THAT keen on mine though, it's a bit flimsy and the peak is a bit too pronounced. But then it was £10.

Plan to get one of these (pattern on top right image) to make up for it
