Taffeta.

The words conjures horrible images of hot pink, pouf sleeves, and bubble skirts. Did someone say "prom?"

Not to worry, Party Princess! The woeful days of taffeta are gone, thank goodness, and the semi-stiff, semi-shiny fabric has grown up into a sophisticated cocktail dress. Anne Klein's Lace Bodice Taffeta Party Dress is perfect for any evening soiree. The skinny little spaghetti straps are a touch of modesty for bare shoulders. The sweet lace bodice gives way to an iridescent taffeta skirt in a deep, rich copper color, which is layered from underneath with tulle for fullness. The ruched sash at the waist means you can snack all you want on hors d'ouevre without worrying about a bulge. For this little dress, I'd go with gold accents all around to match the shine of the dress.

The dress is $198 at Nordstrom.
