Glitter refers to the quality that some materials have to shine with brief sparks or bright flashes of reflected light. Rhinestones and sequins are examples of shiny, decorative adornments that glitter and are generally used to enhance the appearance of evening footwear or clothing.
About Pumps:
Pumps are heeled shoes that are typically tapered to a point or a narrow square toe. The upper of a pump covers the heel and sides of the foot, leaving the top of the foot exposed, which allows the wearer to slip on the shoe.
