I am going to a 6:30 p.m. December wedding in Charleston, SC, that is black tie/evening dress unifrom invited. What kind of dress should I wear?

I would wear something sprakly... that's always fun... but not too showy..

I would pick a dark or neutral colored dress that is simple and maybe do your hair up and wear earrings and heels and such. Don't wear white as it's not polite to the bride. Don't dress up like the queen of england or anything but perhaps a black party dress, knee-length?

Something long and elegant. If it is a black tie event the men are typically expected to be in a tux. You might be able to get away with a cocktail length dress if it is dressy enough, but to be on the safe side go for long. Stick with darker colors; dark blue, black, dark green, dark purple.

Here's a site with some info about what to wear to a specified dress wedding:
