For example:
* Trainers not permitted. I wear multi-sport/walking shoes which have attracted complaint until I explain they are not trainers, just fabric shoes.
* No denim. I wear jean-style trousers made from cotton-duck aka Chinos. These have drawn complaint until I explain that Denim is a specific weave (oblique) and Duck is different (horizontal)
* Shirt with collar. I wear polo-style T-shirts.
Such a subversaive, man you’re craaaaaazy, fabric shoes eh?
