What's your thoughts on this offensive dress?

One of the stories in British newspapers this week is a girl got sent home from school for wearing an offensive Union Jack flag dress. Students were told to dress up in something that reflected their culture and background. While children of other ethnicities came in their national dress, this British girl slipped on a flag dress and was immediately booted out in case it offended anyone.

So thoughts? Is she a dangerous far right extremist just looking to stir up the race hate shitpile? Was it ridiculous for the school to have an event like this when the English don't have an official national dress? Or is it just the tabloids making a mountain out of a molehill?
