I like to pair my statement skirts with a fine-gauge black turtleneck blouse or sweater - something with a slim cut. Black tights or sheer hosiery, with black heels or boots (flat or heeled). Pearls or a sparkly necklace to finish, depending on my mood.
So basically, following Angie's Statement Skirt + Black Supporting Act, as linked above
For a topper, it depends on the event and the venue. If it's going to be cooler inside, or more casual, I would keep on a leather moto, or fabric-style bomber jacket. If the event is dressier, and I know they're going to keep the heat on, I would wear a dressier wool coat and check it.
I would also pair this skirt with a light-colored blouse and/or sweater, nude hosiery and nude pumps.
