What was your prom like? Or, your child's prom? Is prom only an American thing?

I’m watching the show Katie and they are talking about proms. She said it is an American thing, I never knew that. Is that true that other countries don’t have proms?

What was your prom like? Was it in the school gym? A hotel? A dance hall? Was there dancing? Dinner? Appetizers? A theme? Did people go even if they didn’t hate a date? Did the men wear a tux? Did you rent a limousine? How much was the total cost for you?

Was prom a big deal to you? A right of passage? Just another party?
