Good point. I'd add a "usually" to the conservative and formal in that case, but ... yeah.
What is the policy of private and public schools about wearing their uniform out of school?
Very little idea on that, although I thought one of the excuses for uniforms at public schools in places like SoCal was to avoid attracting gang attention on the way to and from.
More generally, the uniforms (both public and private) I've seen have not generally been confusible with something anyone would wear voluntarily, either formal or casual. It strikes me that that the only time that's likely to be an issue when traveling by air is for a school trip... and if you're on a school trip in J or F... well... dang, that's one posh school.
