We agree then!
The (inner) paddocks at the Revival that require a pass have a clearly defined dress code. That code does not apply to the general public areas, although enthusiastically encouraged by all the PR.
MM publicity also
encourages a certain standard of 'dress', but as mentioned by several posters, no one seems to have suffered by choosing to wear their choice, or to suit the conditions!
The house system and games are completely lost on me, not having attended a public school. Again, not compulsory.....
