The basic design for a clutch bag is an articulated frame with a cloth bag wrapped around it. You pull it open at the top. They are meant to be held or clutched and their basic idea is easy and convenient access to whatever they might contain. Besides, they come in a wide variety of materials, colors, and patterns, so if you just keep looking you’ll be sure to find one that matches your dress perfectly.
Most clutch bags are fairly small, about the size of a men’s wallet, though some can also be bigger. Generally, they are meant to carry small essentials like lipstick, a makeup kit, and maybe a bit of cash. They don’t usually have straps and are supposed to simply be held as part of a dressy outfit.
Most clutch bags are in small size, which makes them easy to lose. So remember to keep an eye on your bag and remember where you left it last.
