If you are looking for a sexy short prom dress and a new short prom hairstyle, Rihanna offers fresh styling ideas from her recent red-carpet appearance.

The very popular black star's hair is extremely short on the sides but she has a fairly long fringe. The spiky or "saw-tooth" look is strong and not for everyone; but it's different and will help you stand out from the crowd.

The cobalt blue evening dress Rihanna wore to the 2009 Grammy Awards is adorable! It is short, but not extreme; it falls just above the knee.

The structure is equally sweet and sophisticated and the fabric choices make it look fun and flirty. It is a very elegant dress and would be a good selection for prom if it suits your personality (extreme extrovert).

The bold glamorous night look is completed with bright red fingernails and toenails.
