Just make sure the SC fits very well or you'll look like a security guard. I have worn a black SC to a few evening events (clubs, bars, Vegas, etc). My style for these outfits may not have been fully SF approved. Some may even say it borders on hipsterdom.
In the past I've worn the black SC with:
-grey prince of wales slacks, burgundy tassel loafers, white shirt, gingham PS, burgundy cardigan
-midnight blue corduroys, black lace up brogue boots, white shirt, grey cardigan
-white jeans, burgundy loafers, denim/chambray shirt, black knit tie
