Is this for a formal occasion, like a wedding? Do you want a script typeface?
Lacking any details, I would recommend Capucine.

It's for an art exhibition opening, so probably not a script. I like Capucine! Good suggestion! Thanks! Any others you might have based on the new info would be greatly appreciated. Thanks again!
