The only dress code I'll ever abide by is the one that says cover up your arse and goolies in public at more or less all times and do not be a topless chap in shops and restaurants. I rarely wear long trousers, I don't know how to tie a tie and I have one suit that I last wore in 2002. In my opinion no-one has any right to tell anyone else what to wear.

No one has the right to tell you what to wear, but they do have the right to deny you service.
