Complementary Styles

Ultimately, the most important consideration when he's deciding what to wear to your beach wedding is that your groom matches you. If you're wearing a light sundress, he doesn't need to be wearing a tuxedo. Likewise, if you're braving the beach in sky-high heels and a mermaid gown, your groom shouldn't be in jeans and a T-shirt. A navy suit is an ideal middle ground that can be dressed up or down. Either way, his style should complement yours — and vice versa. Now that's a perfect partnership.
