Everyone's Trying To Figure Out What That Is Around Billie Eilish's Ankle

Ok, I am so confused by this new fashion trend Billie Eilish has going on.

And before you ATTACK me for saying anything about Billie, I'm not being negative or saying she shouldn't do what she wants!

I'm just trying to figure out what that is around her ankle!!

Like is it a small Gucci purse?

Or a Gucci ankle pillow??

And does Gucci actually make ankle pillows?

And what would an ankle pillow be used for??

SO MANY QUESTIONS!!
