Lol no, it won't clash. Black and gold always compliment each other. Though if you want to spice up your look, I suggest changing the color of your heels;
I went to a little black dress party a couple weeks ago, in a black mini dress with some knock out red heels, complimented with gold and red accessories and lipstick. The splash of non traditional color (red) added some dynamic to the outfit.
But black and gold won't clash at all - plus most the guys will be too distracted at how gorgeous you look to breakdown fashion rules lol
