Lighter colors like pastels, soft neutrals, and bright whites are not only perfect for summer weddings, but can also help reflect sunlight, keeping you cooler throughout the day. Avoid dark colors, which absorb heat and can make you feel warmer than necessary. 

Keep accessories minimal and lightweight to avoid adding unnecessary heat. Opt for statement earrings, delicate necklaces, and chic hair accessories that complement your outfit without weighing you down. A stylish sun hat or lightweight scarf can also provide additional sun protection.
