Need Help Finding Colors To Match My Dress

I am having the hardest time trying to figure out what colors to have at my wedding. I found the perfect dress, but it is a gold color (light gold-champagne). I would like my attendants to wear chocolate, but that will not go with the groomsmens` suits (they are all wearing black). I thought about ivory, but I do not know if it is okay to have the girls in a lighter color than me (after all, I am the bride). What about coral?

My wedding is in June. Please help!!
