Ethical Wedding Guest Outfit Ideas For 2025

Going to a wedding in 2025? Not sure what to wear? We’ve got some gorgeous ethical wedding guest outfit ideas for you!

By Bec Gregory

Yay! You just got a gorgeous wedding invitation. But as soon as you send the RSVP to confirm your attendance, you’re faced with the issue of what to wear.

When choosing a wedding guest outfit, there are many factors to consider. These include:

• the season and location of the wedding
• appropriateness of the outfit
• what makes you feel comfortable
• what’s within budget
• and if you care about people and the planet, the ethics behind the outfit.

So, what do we mean by that, exactly?

Our clothing decisions either help or harm the planet, people, and animals. As most of us know by now, the fashion industry is one of the most polluting industries in the world. But it’s also known for exploiting workers, particularly women and children in developing countries. Additionally, the use of animal products, such as fur and leather, involves cruelty. 

Fashion labels that create ethical outfits prioritise eco-friendly, sustainable production, reducing the industry’s environmental impact. They look after their people at all stages of production, paying fair living wages, providing safe working conditions, and offering training and career development opportunities. Animal welfare is also prioritised by using animal-free materials.

What to look for in ethical wedding outfits

The first thing you should do when looking for ethical wedding guest outfit ideas is to check out the websites and socials of the brands that caught your eye. Because when labels are doing good, they will shout about it! 

Below are the kinds of questions we ask to see if a brand is ethical.

What materials are used?

Look for clothing made from sustainable materials with a lower environmental impact. These could include Tencel, organic cotton, linen and hemp, or recycled/upcycled materials.

Who made the outfit?

We’re talking about brands that look after their people. Ethical clothing brands are transparent about their labour practices, pay fair living wages, provide safe working conditions, and offer training and career development. Some certifications and awards to look for include Fair Trade Certified, GOTS (Global Organic Textile Standard) or WRAP (Worldwide Responsible Accredited Production).

Were any animals harmed or exploited?

Look for ethical wedding guest outfit ideas that have been created without harming or exploiting animals. Opt for clothing made from vegan and cruelty-free materials. 

Does the brand support small-scale, artisanal production?

Supporting local artisans preserves age-old techniques, and supports handmade one-of-a-kind pieces. Plus, it helps to move away from homogenised mass production. Look for clothing produced on a smaller scale that reduces the environmental impact and supports local economies and region-specific crafting techniques.

The ‘Birch’ is a chic maxi dress with a fitted bodice and super attractive side split. The simple yet visually exciting design elements work together to create a beautiful, ethereal look. We love the pretty green print! It’s soft and subtle, yet still vibrant and eye-catching. This would look stunning with gold sandals and jewellery, don’t you think? Got an evening wedding coming up?

6. Lisa Linen Midi Dress 

You can feel the loving energy woven through every stitch in this striking handmade midi dress by Nich Linen! It’s both comfortable and chic. The ruched waistband gives the illusion of a smaller waist and adds interesting texture, whilst the ruched cuff on the ¾ sleeves elongates the arms. The A-line skirt skims over the hips and flows into a gentle flare, creating a sophisticated, feminine silhouette. The vibrant electric blue hue is a universally flattering colour that looks great on all skin tones. Linen fabric is lightweight and breathable, making it a perfect choice if you’re looking for ethical wedding guest outfit ideas for outdoor ceremonies.

7. The Bergen Dress 

This dress by Christy Dawn is a carefully crafted long-sleeved maxi dress with a wrap closure. A delicate array of earth-tone leaves and flowers dance across a soft white backdrop giving the look a free-spirited feel. The beautiful, full-length balloon sleeves add a touch of romance whilst providing extra coverage. We love how the V-shaped neck helps to create the illusion of a longer, leaner torso. In addition, it’s bra-friendly (whew!), flattering on all body types, and a joy to wear! 

Price: Around $350

It’s An Ethical Wedding Guest Outfit Because: This dress was crafted from deadstock rayon, naturally dyed using flowers and berries. But that’s not all! Christy Dawn does much more than treat her people ‘fairly’. She says she has formed loving, lasting relationships and brought financial growth to her community of workers.

8. The Elaina Dress

The Elaina is the perfect dress for rose lovers. It comes in a dusty rose hue, and features the flower in the form of appliques on the shoulder straps, breast and hips. Its slinky, short cut is perfect for evening weddings, but its flowery vibes also makes it suitable for daytime ceremonies. 

Price: Around $125

It’s An Ethical Wedding Guest Outfit Because: The dress is made of polyester, yes. But that polyester comes from recycled bottles. And in addition, it’s only made to order: so put your order in well before the date of your event!

9.  Laurel Frill Dress 

The ‘Laurel’ dress by Zimmermann is simply stunning! Designed to add shape and definition to the waistline, the dress is gently gathered across the bodice and cut out at the back. 

The combination of the floral print and the multiple frills make this a super feminine choice, ultra-summery choice of dress.

It’s An Ethical Wedding Guest Outfit Because: Zimmermann is driven by their mission “to make beautiful clothes in a beautiful way”. They use eco-friendly fabrics and donate leftover fabric to smaller labels. In addition, they digitally print their designs onto fabric, which uses around 60% less water than screen printing. Finally, Zimmermann also engages in collaborative projects to advance sustainability in the industry.

10. River Classing Dress

And now for something completely different! This River cutout dress is by Johanna Ortiz. Her unique designs are made in Cali, Colombia which is her home town. She only uses teams of female artisans to craft her garments. This ‘River Classing’ dress features jacquard flowers woven throughout and a plunging V-neckline framed by a subtle cutout and voluminous kimono-style sleeves. Perfect for summer weddings! To keep this looking elegant (as opposed to too ‘beachy’), add some elegant jewellery and gorgeous heeled sandals.
