9. Vintage Balloon and Floral Arch

Instead of modern balloon setups, use muted pastel balloons combined with dried flowers, lace fabric, and greenery.

Create an arch using wooden frames wrapped in floral vines and soft fabric drapes. Avoid overly bright colors and stick to soft tones like beige, cream, dusty pink, and sage green.

This creates a perfect photo backdrop for guests and parents-to-be.
