Are black dresses sexy or boring?

I bought a black dress for this thing I'm going to. . do you think that the color black in general for a dress is boring? Or attractive?

My dress is from cache and it has like a fitted, rouched bottom half and then a blouse-like top. I don't know if you can visualize that but if you can, does it sound cool? I can't post link because I'm not an xper level 4 yet or whatevs

THANK YOU ;)
