9. Cause a scene

Bianca Jagger sitting atop a snow-white horse in Studio 54 entered party lore in 1977. The sartorial equivalent today might not be as outrageous but involves electing pieces that wander far from safe and into disco territory. One shoulder jutting forth from an asymmetrical dress has the appeal of appearing deliberately déshabillé; second-skin sequins highlight the curves beneath; and 3D embellishment is tantalisingly touchable. Choose one and embrace with Jagger-like abandon.
