A mardi gras them is always neat, and decorations are never a lot. Or maybe a Harajuku party, bright neons, some asian inspired decorations.
I'm a party planner in the area, that knows how to work with little or no budget. My name is Camille with Perfect Parties. Email me at perfectpartiesva@gmail.com if you have any questions.
I also know some great places to have them for really good prices.
