From Casual to Dazzle

Black Tie Optional

Translation: Dignified glamour. But a full-fledged to-the-floor, walk-the-red-carpet gown isn't de rigueur; and subtly witty touches keep stodginess at bay. 

To pursue: Rich color, dressy fabrics like velvet and lace, frothy details. 

Variations:To make a quieter (but still grand) entrance, long and flowing is always good.

AKA: "Black tie," "creative black tie," "black tie and long dresses," "bohemian black tie," "white tie," "Texas tuxedo," "gala garb," "formal attire.".
