Think of a "Caribbean Chic" theme, where guests can wear light and airy fabrics in vibrant colors. For men, linen or lightweight suits in pastel shades like light blue, mint green, or beige are ideal. They can also opt for dress shirts paired with dress shorts or khakis for a more casual look. For women, we suggest flowy sundresses, maxi dresses, or elegant jumpsuits in tropical prints or solid bright colors.
