Hi Slim,
Do many of us wear these? Of course not! Don't be daft! They are far too boring! Brown and navy blue? Come on, some of us have some class.
Personally I have just the three, a pink one with black spots for day to day woodworking, a nice gold lamé one for woodworking in the evenings, and a rather daring short one for woody shows. It does, however, have a little bit of lace around the bottom so my knees don't frighten the horses.
I rather fancy the Gucci ones, but you pay a lot for the label.
Cheers
Steve
