Purses that can't stand up on their own will do best with a little assistance from dividers. These not only separate out your bags, but they provide extra support for the shape of the purse. You can also purchase purse inserts or stuffing materials. These go inside of your handbag and help it retain it's shape while it's in storage. Tissue paper and soft packaging materials you already have at home can serve as handy DIY purse inserts.
