I ride a GS scooter with my hair cut neat, I wear my wartime coat in the winter sleet.
So, you'll need a nice 3 button suit,with narrow lapels and six inch side vents, and with a ticket pocket. Bottoms of trousers no more than 16 inches. Button down shirt and tie, no wider than 1 inch. French crop haircut done with a razor only. Vespa or Lambretta scooter with lots of chrome and mirrors. A spanner for those pesky rockers down at Brighton Beach. And a large collection of Sixties soul music as well as the Who, Small Faces, The Jam, etc. Think that about covers it, Please post pictures.
