Hi Jack, a Hungarian themed party is a great idea, I guess you had a great time! You should check the theme of every year's MET Gala. It suggests an idea, but remains very wide and therefore each of the editions are very unique. You can give a quote, a sentence or just and idea, and don't need to be very specific. Here's what I am thinking of: Revival, Neutral, Red is the new black, Versailles, Eccentricity is what makes you unique, Edgy is the new chic… Hope that this helps!
