No prizes for guessing what's the most popular party dress of all time. Yes, it's the little black dress. Predictable? Well, yes. Boring? Not if you work these hottest trends of the moment into your party look. Here are our favorite Fall trends that go so well with the timeless LBD.

1

Sequin LBD

Sequins look especially classy when teamed with black. You can opt for a little embellishment -- or a lot. For the festive season, we much prefer the latter! Like the sophisticated plunge-neck paillette number spotted at Diane Von Furstenberg Fall/Winter 2011 show. All you have to do is to skip the jewelry and let your dress shine.

Peplum LBD

Seen at Chanel, Stella McCartney and Marc Jacobs, the fit-and-flare shape of the ladylike peplum lends shapely curves and sculpts a tiny waist. Plus it's super-flattering to all figures -- whether you're a pear shape or have a boyish figure.

Polka dot LBD

The dotty trend is back this season, but this time around it's shed its retro image in favor of plenty of sex appeal. Rock the polka-dot print in the form of a sophisticated black number and sexy see-through mesh panels, as seen at Stella McCartney. Sexy -- with a capital S!
