Prom is a big deal for high school students, but it can also break the bank.

Last year, teens and their parents spent an average of $919 on the big event.

That number includes spending on things like dresses, tuxes, limos, prom tickets, flowers, pictures, and dinner before the actual prom.

According to VISA, asking your date to the dance is expensive, too!

The average over the top “prom-posal” was $325.
