Handbags are the very core of space, convenience and style. An example of such are Kipling Bags (which I found on PoshBags) and these very lovely Gucci handbags.
Every handbag I've held gives me enough room for everything I need to bring elsewhere. It gives me compartments that is highly needed for every piece of thingamajigs. These compartments serve as dividers and organizers as well.
The above reason also boils down to the convenience of the person using the handbag. Each of us wants to be comfortable and convenient while outside our homes. Thus, being organized is highly encouraged.
Lastly, handbags never went out of style. Thus, you can always count on a good handbag to save your lazy days. You will never have to dwell with those crappy bags that do not give you the space you need.
You just need to be creative with your style and strut your handbag like how a true fashionista does it.
