NEED OPINIONS!!!! ASAP!!!?

So I have a pool party soon and I'm gonna wear this black strapless dress cover up over my red white black and Orange swimsuit...... It's in late afternoon/night and I was wondering what goes Better with black.... White or gold??? I like to wear both and they both ok good but since it is summer and black istnt a summer color should I wear white to liven it up a little???? Or should I wear gold since that looks with black??
