She’s come a long way from sitting quietly in her country outfit, just strummin’ her guitar. She’s now like Late-Stage Elvis (if he had stayed thin), having successfully transitioned from rockabilly star to top Vegas headliner.
I can’t say that she can sing as well as The King, but she obviously is better than Elvis at nutrition and exercise.
Then again, who isn’t? The rest of us couch potatoes are like Jack La-Fucking-Lanne compared to Elvis.

Swift can sing?
1950s underwear maybe.
Exactly like the bathing suits she used to wear!
