Customs uniform senate walks out ali for improper dressing

It seems like you're referring to a rather unusual scenario!

So, to summarize, you're saying that the Senate (presumably a legislative body) has a uniform policy, and a member named Ali has walked out of the Senate because they were not allowed to wear their preferred attire, which was deemed "improper" by the Senate's customs.

Can you tell me more about this scenario? What kind of uniform policy does the Senate have in place, and what was Ali's attire that was deemed "improper"?
