Personally, I prefer to wear black to work, but in the last few years most party promoters are asking us to wear a particular colour- and it's usually black.
To make it stand out, I've been collecting sequinned, beaded, elaborately detailed pieces in all black.
This skirt hits all those notes. Love it. It even has tiny bells on it, so it makes music when I walk.
