For wedding attire that embraces a dressy casual vibe with a tropical theme, consider wearing a light, breathable fabric such as linen or cotton. A floral maxi or midi dress would be perfect for women, paired with strappy sandals or wedges. For men, tailored shorts or lightweight chinos combined with a short-sleeved button-up shirt in a vibrant floral print can capture the tropical essence. Accessorize with fresh floral accents or tropical-themed jewelry, and don’t forget to incorporate bright colors to complete the festive look!
