Mona Kattan's Must Haves: From Her Go-To Scent to a Portable Charger

Kattan loves to keep her bags and purses organized, and the Doxo Purse Organizer Insert ($13–$37) helps her do that. "In every purse, I have a purse organizer because I like to be prepared. I always have a lot of things in my bag, but I don't like it messy, and it just makes it easy to change your bag. I change my bag with my outfit, so it's like in-and-out type of thing," she says.

This insert has 10 pockets, with eight interior pockets and a large zipper pocket divider in the middle. Plus, this organizer has a sturdy construction, so not only will your things stay in place, your bag will also stay structured. It comes in sizes medium to extra large in several different colors as well.
