EARLY FALL WEDDING GUEST BEACH WEDDING OUTFITS

Early fall weddings by the sea are all about breezy silhouettes and fuss free shapes. Choose colours to match the glorious sunset and avoid multiple layers to stay cool under the sun. You also want something you don’t mind getting a little bit sandy and salty. Lastly, don’t bother with heels, and opt for a pair of flats or wedges.

1 SEPTEMBER BEACH WEDDING GUEST DRESS WITH FLAT SANDALS

Flat sandals with a dash of gold will perfectly match any September beach wedding guest dress. Especially those in linen. I’m obsessed with this dress in trendy Bronze Mist and this dress in Primerose Pink.

*Finish the look with a rattan clutch.

Maxi lengths and airy ties are endlessly flattering and really set your heart aflutter.

When it comes to choosing the perfect outfit for an island formal, late summer wedding, or early fall wedding in September, you need an island gown and sandals. The Cult Gaia crochet dress in Lemon Grass will be perfect.

The floor length and fitted bodice give it a touch of sophistication, making it ideal for a wedding party.

As you slip into it, you’ll instantly feel the luxury, promising comfort as you dance the night away.

But what truly sets this dress apart is the golden hand crochet yarn, and sheer fringe, a whimsical detail that adds a playful touch to its elegant design.

3 LINEN DRESS WITH SLIDES AND A HEADBAND

Choice of fabrics is all important for a wedding on the beach. Avoid sequins and too much glitz, and look instead to clean lines that match the beach and low-key surroundings. They can have a print. Or add a headband. Simple accessories, likea headband, will help to make the outfit look extra special.

For a tropical setting, you can bring both into the mix – the print and a headband. Like this!

EARLY FALL WEDDING GUEST FORMAL OUTFITS

If the dress code for an early fall wedding says formal, then really go the extra mile with a proper evening dress or a full skirt.

Be sure to avoid daytime looks with cotton or linen and opt for more luxe styles in silk, taffeta or lace.

4 COCOA BAROQUE BLACK FLORAL DRESS WITH BLUE HEELS AND PEARL HAIR ACCESSORIES

Now is the time to go in for a bit of sparkle, add on those pearly accessories and get statement heels to stand out.

I always feel like a princess in cascading gathered tiers executed with darling floral details. And I know you will love this September wedding guest dress, too. *The photo in the collage was taken in October, so we can say this is an October wedding guest dress, too.

5 PEPLUM BLACK LACE TOP WITH FULL LONG SKIRT AND SLINGBACKS

Now the weather is cool enough to wear jacquard with ease, we love the option on offer. A full skirt offers the perfect balance between looking formal and feeling special.

And when it comes to elegance, class, and embracing the key fall 2025 fashion trend, there’s a combination that beckons to be worn, effortless yet undeniably classy.

Imagine yourself strolling through the picturesque gardens of an elegant estate. The colors of fall foliage paint a mesmerizing backdrop for a formal early fall wedding. And a dark lace peplum top paired with the noble embossed floral jacquard full skirt in Future Dusk in this setting.

As you step onto the beautifully manicured grounds of the venue, the lace top brings a sense of alluring charm. The modern peplum is giving. The subtle sheerness of the lace hints at sensuality beneath the refinement, allowing you to do a classy style with a hint of allure.

Now, let’s talk about that full skirt. The New Look is a key styling trend for AW25. And we are doing the New Look styling principle with a slightly longer skirt for a formal September wedding.

The rich, embossed floral jacquard feels tailor-made (pov mine was taken in, so it should look tailor-made – but even before, this skirt looked exquisite – my seamstress was taken by the fabric – the price though, well here is when I cringe because of the sustainability of its production – but according to my seamstress I will be able to have it for decades, so it justifies the purchase) for this September wedding.

With its full silhouette, it creates a sense of whimsical drama. The skirt’s luxurious texture and embroidery make it the perfect choice for a formal event that demands nothing less than the most elegant attire.

And what better way to elevate this early fall wedding guest outfit than with the slingback pumps?

These are from Roberta Festa. The embellished buckles add an extra touch of class to your overall look.

CLASSY EARLY FALL WEDDING GUEST CHURCH OUTFITS

A church comes with its own set of rules and dress code. Ps. Get your church dress code guide on Brunette from Wall Street substack. Luckily, it is easy to follow all in early September.

9 EARLY FALL WEDDING GUEST MORNING DRESS WITH SLINGBACKS AND FASCINATOR

You stand before the grand entrance of an ancient church, the stone facades looming high above. The air is filled with the hushed excitement of the occasion. It’s an early fall morning, and you’re here to attend your friend’s wedding. The dress code is formal, of course. Formal, and lavish old money. We could say tacky, but we won’t as you will be dressed classy. Fancy, but classy.

Your outfit for this momentous occasion will perfectly encapsulate the class and sophistication. The Self Portrait morning dress will grace your form with its draping silhouette, the luxurious fabric flowing like liquid gold. The dress, cinched at the waist by a sleek belt, exudes an air of regal poise, making it an ideal choice for this church ceremony.

As you enter the dimly lit sanctuary, the stained glass windows will cast kaleidoscopic patterns of light across the wooden pews. The dress will shimmer in the muted glow, catching the eye of fellow old money guests.

Your Amina Muaddi Satin Begum Slingback Heels 95 will leave a delicate imprint on the old, polished floor. And their satin finish will add a touch of opulence to your every movement.

Of course, you will wear a fascinator, too. A Justin Smith fascinator in colors that perfectly match both the shoes and the dress.

10 DOUBLE BREASTED BAR STYLE JACKET WITH A BELT AND MIDI TULLE SKIRT WITH PUMPS

On a crisp September wedding morning, a fashionable ladylike outfit emerges like a breath of fresh air. Imagine yourself in a 50s style outfit, carefully curated for this special occasion.

Start with a black double-breasted Pinko blazer. By the way, you will see me wearing a linen Pinko blazer in the video below – it was quite hot outside. And I didn’t want to wear heavy fabrics. Also, I thought you might want something lighter, too. All in all, it’s still summer outside the church.

Cinch the blazer with a black belt to sculpt a modern silhouette.

Pair the blazer with an inky floral double-layered mesh tulle midi skirt, akin to a garden shrouded in the gentle embrace of twilight. The skirt will dance with every step. Its layers of tulle create an ethereal, whimsical effect that perfectly complements the morning hours. And the inky florals evoke a sense of fall’s rich, moody palette, drawing inspiration from the natural world as it prepares for its slumber.

Accessorise with blue Gianvito Rossi satin blue pumps for a lavish old money touch – perfectly harmonizing with the overall aesthetic while adding a playful twist. Ps. get them in black if you plan to complete this refined early fall wedding guest look with gloves.

11 SHORT SLEEVE SEPTEMBER NAVY WEDDING GUEST DRESS WITH PUMPS

Small and intimate, not every church wedding calls for grand gestures and fascinators. If you want to keep things low-key, look to exquisite tailoring and sleek silhouettes for a touch of glamour that feels just right.

Navy wedding guest dresses always look elegantly poised in a pastoral setting. And the tailoring and structure will lend an elegant air to the formal parts of the wedding.

12 TWEED SEPTEMBER WEDDING GUEST LONG SLEEVES DRESS WITH SATIN HEELS

Daytime elegance comes assured with a tweed dress whlist subtle touches of metallic thread and buttons that add a special touch that doesn’t feel overdone. For that pop of something exquisite, why not add a fashionable weeing guest hair accessory like a headband adorned with diamanté? Or satin pumps? Ps. I was thinking ahead and added bloom satin pumps in the widget below. While blue is the best colour to wear for a September wedding, dark pink reins supreme for a wedding in October.

ELEGANT EARLY FALL WEDDING GUEST BLACK TIE OUTFITS

If you are looking for that grand entrance, length and volume are the best ways to make an impact. Explore styles with full ballgown skirts or slits to create those high drama moments and feel your most beautiful self.
