Anybody elses school suddenly have kids wearing suits randomly?

So this hasn't happened in previous years, usually I'd see 1 or 2 kids if any wearing a suit if they have a big event at school or after school, or they'd wear it on Halloween or Spirit day.

But this year, I've seen at least TEN kids wear a suit on a random day once, and I also know 3 or 4 that have repeatedly worn them on random days. Like is this a new thing? Are suits slowly making a comeback or new trend? Or is this just my school
