A convertible carrying device in which the straps may be selectively secured to configure the device as a backpack or as a handbag. In the handbag configurations, the selective securing of the straps effectuates differing functional strap lengths enabling the handbag to be carried by hand, over a shoulder, or cross body. The arrangement of the connection points on the bag and the straps applies directional forces to the placket surrounding the opening that make it adopt a valley shape when in a handbag configuration and a planar orientation when in the backpack configuration.
