What do you mean "accessories?" Jewelry or things like a purse or a belt?
A belt in a contrasting color usually works, but that would accentuate a waist. If you don't really have a thinner waist, skip the belt.
For jewelry, gold or something that is near to the color of the outfit should always work.
Dangily earrings for a club would be good.
Shoes? When in doubt, go with black.
For a club, pumps or a strappy sandal. If you plan on dancing a lot, you might want to bring some flats with you.
Depending on the club, you might want to get something flashy with crystals or beadwork
