How We Found These Sustainable Wedding Guest Dresses

When it comes to finding sustainable wedding guest dresses, it’s important to consider the materials, supply chain and labor practices, carbon commitments and green practices, inclusivity, and community and charitable giving of the brands.


The use of eco-friendly fabrics is crucial for reducing the environmental impact of a garment. Sustainable brands offer a variety of options, including natural, renewable, plant-based fabrics such as organic cotton and linen dresses. Silk fabric is also a popular choice for formal wear and cocktail dresses, but it’s important to choose peace silk or vegan alternatives like cupro fabric. Semi-synthetics like ECOVERA™ and TENCEL lyocell are also becoming increasingly popular choices for sustainable brands. It’s important to avoid synthetic fabrics like regular viscose, unless it’s pre-loved or sourced from a sustainable brand that uses deadstock material. The most sustainable fabrics are those that avoid toxic chemicals at all stages of production, including non-toxic dyes.

Certifications such as bluesign®, Global Organic Textile Standard (GOTS), OEKO-TEX, and Forest Stewardship Council (FSC) are important indicators of a brand’s commitment to sustainable materials.

Supply Chain & Labor Practices

The most ethical dresses are those made by people who receive fair wages and benefit from a healthy and safe working environment. Regular audits and third-party manufacturing certifications are crucial to ensuring ethical manufacturing and avoiding greenwashing. Certifications such as Fair trade and World Fair Trade Organization (WFTO) are important indicators of a brand’s commitment to ethical labor practices.

Carbon Commitments & Green Practices

In addition to eco-friendly fabrics, sustainable brands can also make a commitment to using renewable energy, localized supply chains, utilizing carbon offset programs, minimizing waste, using recycled materials or plastic-free packaging, and resale programs. These practices can significantly reduce a brand’s carbon footprint.


Sustainable brands should offer fair trade frocks and ethical ensembles for bodies of all shapes and sizes. Inclusivity is an important aspect of sustainability.

Community & Charitable Giving

Brands that give back to their communities through charitable donations, volunteer events, and employee training and support are making a positive impact on the world.

Final Thoughts On Eco-friendly Guest Dresses For Special Occasions

Sustainable wedding guest dresses are a great way to dress up without bringing the planet down. Second-hand scores from local thrift shops or online shops are a great sustainable option. Supporting sustainable brands that prioritize eco-friendly materials, ethical labor practices, carbon commitments, inclusivity, and charitable giving can make a positive impact on the fashion industry.
