For a playful and retro-inspired look, choose a polka dot dress for the Movers & Shakers baby shower. Polka dots are a timeless pattern that adds a touch of whimsy to any outfit. Opt for a dress with a fitted bodice and a flared skirt to create a flattering silhouette. Pair it with some vintage-inspired accessories like cat-eye sunglasses and a red lip for a truly retro vibe.
