Women should opt for a sundress, breezy maxi dress, or high-quality romper. And while dressy sandals are acceptable, avoid standard, beachwear flip-flops.
Men can do short-sleeved shirts, such as polos, linens, nice shorts with a belt etc. In general, stick with lighter colors and/or bold prints.
Women, feel free to include prints, avoiding anything too loud or any style that might clash with the venue. If you choose to wear a beachy dress, specifically, consider it in either tea-length or maxi to avoid looking too casual. Dressy sandals, chunky heels, and wedges are acceptable footwear options.
For Men, while a jacket isn’t required, a breathable sport coat can be a fun addition. Feel free to include prints, avoiding anything too loud as well. Popular beach styles includes camp and cuban collar shirts, linen fabrics etc. Shoes can be a little more casual such as a loafer, deck shoe or sandal. Have fun with outfits and don’t think too much!
