Hi,
It sounds like there are many different outfits that could suite you. Basically it also depends on what you're used to wearing since that's what wearing something different is all about.
I would go with an elegant dress, something you feel confident in but not loud. Perhaps you would like to wear some gold jewelry that would go great with your complexion. Add on that a pair of classy high heels and you'll be the star of the party.
Hope you enjoy yourself. Take care.
