This year we're taking a vow: We're cutting down on the clutter we lug around in our clutches and purses on nights out. After all, do you really need four lipsticks for one evening? One way to stick to this promise: Downsize your bag. Louis Vuitton, J. Mendel, Lanvin and other fashion houses sent tiny, structured box clutches -- with just enough room for your cellphone, credit card and one lipstick -- down the fall runways.

With funky square and rectangular shapes, gilded and bejeweled details, and funky zippers and tassels, these box clutches are diverse enough to fit every personality.

This brass-plated Sophie Hulme clutch is a unique take on the designer's signature brass-detailed bags and totes. BET host Rocsi Diaz wore the gold-and-navy box clutch to this year's Grammy Awards.

When Louis Vuitton debuted this Petite-Malle bag at Paris Fashion Week, it was dubbed the "It" bag of the year. The trunk-style box clutch comes in the brand's signature logo print, cognac leather, gold metal and several other shades.

The Lanvin fall/winter 2014 New York Fashion Week show embraced fringed everything. In the case of this eggshell leather box clutch, a tassel purse charm does the trick.

This gold, glittery box clutch looks luxe, but it's actually a simple DIY project from Australian lifestyle blog & Other Things. Simply take a see-through Lucite or acrylic clutch, measure the material you want to fill it with and secure the material with double-sided tape if it doesn't fit snugly on its own.
