An Elvis impersonator is someone who dresses up and acts like Elvis Presley, the famous rock and roll singer. They might wear shiny jumpsuits, slick back their hair, and even sing and dance like Elvis did.
Why do people want to be Elvis impersonators? Well, Elvis was a very famous singer who lots of people loved. When he died, many people wanted to keep his memory alive and honor him by pretending to be him. It's kind of like playing dress-up, but for grown-ups!
Some Elvis impersonators perform at events like parties or weddings, while others compete in contests to see who can be the best Elvis lookalike. It can be a lot of fun to watch, especially if you're a big Elvis fan yourself!
