For most teenagers, getting ready for the end-of-year prom can be an arduous and expensive process.

From finding the perfect dress to sorting hair and makeup, preparing for the big event can take some organisation.

But when 18-year-old Elle Mills crashed one high school prom wearing just pyjamas and sneakers, she managed to have a ball.

The YouTube star, from Ontario, Canada, posted on Twitter, “I tried to subtly crash a prom.”
