Suit & Tie
Translation: With this dress code, women wonder, So what do I wear? The answer: pulled-together, not-too-naked stuff. The flared skirt here is flirty but not risqué—silk and satin evening fabrics add a certain mad extravagance. 

Variations: Its slightly formal connotations make black-and-white totally appropriate. Bare legs? No problem. And you can go a little crazy on accessories. 

AKA: "Bring your suit," "dark suit," "jacket requested," "dark and chic," "semiformal."
