Mom Wants A Swift Themed Retirement Party

Help! I (40f) have been tasked by my Mother (65f) to plan her retirement party. I knew it would be one of us (my sisters 36f and 43f respectively) or me to do so and I was prepared, but she threw me for a loop when she said her preferred theme was T Swift. See, she and my Father recently discovered Taylor through watching the Eras Tour and are now \*obsessed\*.

I grew up with Taylor's music around but I know diddly squat about lore. Resolute I am, however. Determined. I could ask my sisters to take over, but they hate Taylor Swift and I know they wouldn't be likely to honor Mom's wish and she'd back down to make \*them\* happy. She is very into Showgirl right now, and Im reserving a dining room/party space at a wine bar that could work on brand.

If you were throwing a party with a Life of a Showgirl theme, what would you include/like to see?
