You just got the invite. It’s a beach wedding. Your first thought is probably "paradise," but your second thought is definitely "what on earth do I wear?" It's a tricky balance. You want to look sharp for the photos, but you also don't want to be the person sweating through a three-piece wool suit while the groom’s aunt fan-kicks sand onto your polished oxfords.
Dress codes for coastal ceremonies are notoriously vague. "Beach Formal" is an oxymoron. "Tropical Chic" sounds like a drink order. Honestly, most people overthink it and end up looking either like they’re headed to a board meeting or like they’re ready for a shift at a margaritaville bar. There is a middle ground.
The Fabric Choice Will Make or Break Your Day
If you remember one thing from this, let it be this: Natural fibers are your only friends. Polyester is a portable sauna. In a humid coastal environment, synthetic fabrics trap heat against your skin, leading to those dreaded sweat patches before the "I dos" even happen.
Linen is the undisputed king of the coast. Yes, it wrinkles. Embrace it. That lived-in look is part of the charm and signals that you understand the environment. If the thought of wrinkles gives you hives, look for a linen-silk or linen-cotton blend. The Italian concept of sprezzatura—a kind of studied carelessness—is exactly what you’re aiming for here.
Seersucker is another heavy hitter. It’s not just for Southern lawyers; that puckered texture actually holds the fabric away from your skin, allowing for better airflow. It’s physics, basically.

For the Ladies: Length and Movement
Floor-length gowns are stunning, but they act like a literal vacuum cleaner on a beach. By the time the reception starts, the bottom six inches of your dress will be damp and grey from the tide line.
Go for a midi length or a high-low hem. High-low might feel a bit 2014 to some, but in a beach setting, it’s remarkably practical. It gives you the drama of a train without the maintenance. Chiffon, organza, and lace are great because they catch the ocean breeze. You want movement. If the dress doesn't flutter when you walk, it's too heavy.
What "Beach Formal" Actually Means
When a couple puts "Beach Formal" on an invitation, they are usually asking you to respect the gravity of the event without dying of heatstroke.
For men, this typically means a suit, but leave the black and charcoal in the closet. Think light blue, tan, cream, or even a pale sage green. A tie is usually optional unless the couple is very traditional. If you skip the tie, make sure your shirt collar is crisp—nothing looks sloppier than a sagging, sweat-wilted collar.
For women, "formal" implies a more sophisticated fabric. Think silk or a high-end crepe. You can definitely do a jumpsuit here. A well-tailored, wide-leg jumpsuit in a vibrant coral or deep turquoise looks incredibly chic against a sunset backdrop.
The Shoe Situation (The Great Sand Trap)
Stilettos are a death wish. You’ll spend the entire ceremony performing a balancing act or sinking six inches into the dunes. It’s not graceful.
- Block Heels: If you need height, a chunky block heel provides the surface area to keep you above ground.
- Fancy Flats: Don’t sleep on a metallic, embellished slide.
- Espadrilles: The ultimate Mediterranean wedding choice.
- Go Barefoot: Some couples encourage it! But always have a backup for the reception.
Men have it slightly easier but still face pitfalls. Suede loafers are great, but salt water and sand can ruin them. Consider a leather loafer or a clean, leather boat shoe (not the beat-up ones you use for actual boating). If the vibe is truly casual, a high-end leather sandal can work, but your feet better be camera-ready. No one wants to see unkempt toes during the cake cutting.
Navigating the Color Palette
Black is usually too harsh for the beach. It absorbs heat and looks out of place against the pastel hues of the shoreline. Instead, look toward the horizon for inspiration.
Muted earth tones—think terracotta, ochre, and olive—work beautifully for "boho" beach weddings. If the wedding is at a high-end Caribbean resort, lean into the "Preppy" look with pinks, yellows, and mints.
Pro Tip: Avoid anything that perfectly matches the bridesmaids. If you aren't sure what they’re wearing, ask. Usually, they'll be in some variation of seafoam, champagne, or dusty rose. Pick something that complements but doesn't mimic.

Real Talk: Practicalities No One Mentions
Wind is a factor. A short, flouncy skirt might look cute in the mirror, but one gust of Atlantic wind and you're giving the guest list a show they didn't sign up for. Weight your hems or choose a more fitted silhouette if you know it’s a windy coast like the Outer Banks or the cliffs of Portugal.
Sunscreen is non-negotiable, but choose a matte finish. You don't want to look like a glazed donut in the professional photography. Also, sunglasses! Bring a pair that looks "dressed up." Your sporty wraparound shades for cycling don't belong in wedding photos. Go for a classic Wayfarer or Aviator.
The Groom and Groomsmen
If you’re in the wedding party, you’re at the mercy of the couple’s vision. However, if you have a say, advocate for unlined jackets. A standard suit jacket has a polyester or silk lining that acts like an insulator. An unlined or "half-canvassed" linen jacket is a game changer. It feels like wearing a shirt but looks like a suit.
Next Steps for a Flawless Look
Check the specific location on Google Maps before you shop. A "beach wedding" at a resort in Cabo where the ceremony is on a paved terrace is very different from a "beach wedding" on the actual dunes of Malibu.
- Audit your closet for 100% linen or cotton pieces first.
- Invest in a "no-show" undershirt if you're prone to sweating; brands like Thompson Tee make versions specifically for high-heat events.
- Book a pedicure two days before the event if you plan on wearing open-toed shoes or going barefoot.
- Pack a small "beach kit" including oil-blotting papers, a travel-sized hairspray (for wind control), and a few safety pins.
Avoid the "costume" trap. You aren't dressing up as a pirate or a castaway; you're attending a formal union in a challenging climate. If you feel like you're wearing a costume, you probably are. Aim for a refined version of your best self, just with a little more airflow.
