Abstract: Disclosed is a modular handbag system that allows the user to select one or more pockets to be inserted in a bag. Each pocket has attachment means to secure the pocket to the interior of the bag and the pocket can be changed whenever desired or if there is more than one pocket, the entire pocket structure can be relatively easily removed from the bag and secured into another bag. This allows the user to change purses to match needs or outfits and allows users to have a bag with exactly the number and size of storage pockets they want at any given time. Knowing that the inside pockets can be customized allows users the freedom to choose an outside look to suit their style, without being frustrated by the interior storage capabilities.
