28 Best Wedding Guest Dresses Of 2025 You’ll Want To Wear This Wedding Season

I have six weddings to attend this summer, one of which calls for 'colour' in the dress code. As someone who struggles to wear anything other than black, brown and navy, I knew this would be a challenge - then I found Nobody's Childs range of vibrant wedding guest options. The balloon-sleeve style felt like something I hadn't seen before, and I was immediately taken by the vibrant green hue. It was comfortable, cinching at the waist, and the a-line skit was very flattering on my legs. Safe to say, this is a strong contender.

Wearing black to a wedding is sometimes frowned upon, but you can definitely get away with it at a black tie event. Rat & Boa's selection of brilliant wedding guest options makes choosing impossible, but the black ruffled Selena style immediately caught my eye. It's flattering, delicate and a compliment machine. Word of warning - if you're under 5"4, this will definitely need hemming. For Black Tie dress codes, make sure to accessorise appropriately - gold or silver heels, a statement necklace or earrings, and the perfect clutch. To beat the evening chill, drape a blazer or silk scarf over your shoulders.

I wore the this balloon dress Nobody’s Child to a spring wedding, and it struck the right balance between pretty and polished. The v neckline and soft balloon sleeves gave it a romantic edge, while the midi length kept it classic. Easy to wear, flattering, and didn’t need much styling - just heels and a clutch.

The Mango asymmetrical straps is a stylish, high-street gem that feels far more expensive than it is. The one-shoulder ruffle detail and soft floral print give it a romantic feel with a modern twist—perfect for weddings, garden parties, or summer events. The fabric is light but fully lined, making it comfortable enough to wear all day, and the straight-cut silhouette is surprisingly flattering across different body types.

I can't dream up a better summer wedding guest style if I tried. The Novie halter neck exudes understated elegance with minimal effort. The halter neckline and open back added a modern edge, while the bias-cut skirt skimmed the body in a flattering way. It felt light and breathable, ideal for warm-weather occasions.

The Significant Other Merida Gown is one of those dresses that turns heads without trying too hard. The vibrant floral print feels bold yet romantic, while the crinkled fabric gives it an effortless, thrown-on charm. Its deep V neckline and open back with twisted straps offer a modern twist on classic occasionwear, ideal for summer weddings or destination soirées. Light, breezy, and undeniably chic -it’s the kind of dress you’ll be glad you invested in.

Mango'sone-shoulder linen dress is a minimalist summer staple that feels both polished and effortless. Crafted from 100% linen, it offers breathability and comfort, making it ideal for warm-weather occasions. The asymmetrical neckline and draped waist detail add a modern twist to the classic midi silhouette, while the side slit enhances movement and adds a touch of allure. This dress is versatile enough to be dressed up with heels and statement jewellery for events or paired with sandals for a more casual outing.

The Mango asymmetrical satin dress with fringes is designed for those 'main character' moments at weddings, parties, or elegant evening events. Cut in a lustrous satin finish that catches the light beautifully, this midi-length piece makes a sleek statement without shouting. Though the fit is straight and slightly relaxed, the fabric skims rather than clings, making it a flattering choice for a range of body shapes.

Abercrombie's Giselle Halter Maxi Dress is a standout choice for wedding guests or summer soirées, offering both comfort and polish in equal measure. Designed with input from Abercrombie’s fit specialists and part of their elevated occasionwear range, it features a halter neckline, smocked back panel for flexibility, and a sweeping maxi skirt with subtle volume. The fabric is lightweight and fully lined -ideal for warm-weather events - while the darted bodice adds subtle structure for a flattering, tailored feel.

Polka dot dresses are out latest obsession, and the Abercrombie & Fitch midi is crafted from a lightweight fabric, this dress features a fitted bodice that accentuates the waist, leading into a flowing midi-length skirt with godet inserts that add volume and movement. The clasp-back detail offers a modern twist, ensuring the dress stands out at any event.

Being 5"2, finding the perfect wedding guest dress is a challenge, and often times getting a dress hemmed is not always a quick and easy solution. That's why Whistles' petite collection immediately intrigued me and unsurprisingly, fit like a glove. The smocked dress exemplifies contemporary British design at its finest, marrying expert tailoring with everyday elegance. Crafted from 100% breathable cotton, this midi dress features a precision-engineered smocked bodice that contours comfortably to diverse body shapes, offering both stretch and structure. The delicate puff sleeves and subtly flared skirt are thoughtfully proportioned to flatter a wide range of figures, ensuring versatility from garden parties to smart-casual work events.

For a more relaxed nuptial ceremony, the Mango puffed hem dress is a strong contender for those who want to move away from classic occasionwear without sacrificing polish. Cut from a cotton-blend fabric, it balances structure and softness - fitted through the bodice with a dramatic puffed hem that adds sculptural volume. Part of Mango’s premium Selection Collection, this dress is crafted with attention to detail: the seamed waist and discreet semi-sheer finish give it a considered, high-fashion feel.

This daisy-printed sleeveless dress will definitely win the battle of the florals on the dance floor.

A muted take on a floral dress for Reformation, the silky fabric gives a perfectly luxurious feel. Wear it on its own for summer weddings, or add an oversized blazer when it's cooler.
