It's been a while, but extra long leggings on BOTH of Elizabeth's legs are nice to see too. But as you know, she is best known for wearing only on one leg.... She could have made a visual pun if she only wore the arm coverings on just one arm.
Just like her long arm coverings aren't gloves as they don't cover the back of the hand and palm, leggings aren't stockings as they don't cover the feet even though she is improperly trying to wear the leggings over her heels as if they were partially stockings.
