Have a beach wedding on the calendar? With the backdrop of crashing ocean waves and salty seaside breezes, beaches are not only a serene and romantic venue to tie the knot, but they also lend themselves to exciting wedding fashion. From flowy maxi gowns to ruffled mini frocks, you're no short of casual and elegant beach wedding guest dresses for your forthcoming coastal affair.

While shopping for dresses to wear to a beach wedding as a guest, there are a few things to keep in mind, including the fabric, silhouette and color of your dress. Prioritize summer-friendly materials, including linen and cotton, that are breathable and moisture-wicking. Shorter hems, flowy skirts and vibrant colors and patterns (think: florals, stripes and polka dots) are also welcomed on the beach. As for your accessories—have fun with them! A stylish sun hat, a rattan purse and heeled sandals or dressy wedges are all great ways to elevate beach attire.

Although most beach weddings err on the side of dressy casual, black tie and formal attire are not completely out of the question. Therefore, it's always a good idea to confirm the dress code of the event before making your final purchase. For even more tips and tricks, check out our detailed beach wedding attire guide.

To give you a headstart on your search, we've handpicked our favorite wedding guest dresses for the beach, below. Whether you're attending a tropical destination wedding or a local seaside soiree, keep scrolling for casual and dressy options for every style and formality. Let's dive in.
