When thinking of beach weddings, there's one thing that must be considered before heading out to grab all your stuff, and that's the theme and clothing. You have to make sure you set a theme that is consistent and something that works with the location. It shouldn't necessarily be casual as it can be a formal event if you want it that way, however, simplicity is recommended. The weather will likely be hot, so comfortable and airy fabric is the choice most go for. Men could try linen options as it is a very breathable fabric and women can opt for something cotton or linen, ideally a sundress.
