Special occasion or evening bags come in a variety of different shapes and
styles. They can be mini-clutches, drawstring bags, small shoulder bags or any
other variety of bag. Whatever shape and style, evening bags are normally shiny,
featuring patent leather, sequins, crystals or jewels. Hard case clutches made
of metal or hard plastic have grown in popularity in recent years.
