As many have explained, the cold snap in Florida was unexpected. They just flew in from wherever, and there wasn’t time to stop by an upscale store for a different coat. The shoes are a perfect color match and suited her athletic personality better than the fashionistas’ strappy sandal heels. The sartorial snobbery is unwarranted.
It’s called being properly well dressed for the occasion. That’s how I was raised, it’s not snobbery.
