We had to wear horrible purple and grey, most unflattering! Hats were compulsory - grey felt bretons in winter and stiff boaters in summer (actually the boaters were quite fun and attracted a lot of attention from tourists, and we used to scrunch up our bretons behind our back-combed hair). Grey gloves in winter, white in summer, and occasional 'glove inspections' at the gate to make sure we were correctly dressed! Ugly, clumpy shoes, thick socks or 60 denier stockings; a summer dress that looked like a florist's overall. Everything quite deliberately designed to make us look as dowdy as possible, in fact!
