9. Balloons Galore!
Food and alcohol add up quickly. Fortunately, you can cut costs with your décor. One super Kate Spade-esque detail to include at your party is balloons. Purchase letters off Etsy or regular black and gold balloons from your local Party City. Whichever you choose, balloons are a fun way to fill the space while staying on theme, and they can help designate where people are supposed to park once they arrive at the party site!
