Just came across this thread.
In the zippered "flap portion" of the bag, I place my LV wallet. It's flat and when the flap is zipped, I know my wallet is always secure.
In the main compartment that's held together magnetically, I carry my sunglasses, AP, packet of tissue, hand-sanitizer etc....
And the outer back zip compartment (which is a generous size! LOVE it), holds my precious iPhone.
I LOVE LOVE LOVE this bag!!! It's my fave bag right now......NO urge to change out of it....none whatsoever!
