They allowed me to bring in my small purse that I could wear over my shoulder, it was not clear

The 2022 bag policy allows one single compartment 5 by 9 clutch (not transparent). As the season wore on, they are allowing larger clear bags so I think your small clear bag will be fine.

You can bring in a small clear bag about 5"x5".

You can bring in a clear bag or a small purse about the size of a cell phone..give or take.

They allow a clutch

Yes, make sure it’s small.
