In honouring Earth Day and the signing of the Paris Agreement on Climate Change, we here at Twenty3 are celebrating fashion brands who are doing their part by putting  sustainability first, every day — not just on Earth Day. From apparel to shoes and accessories, here are 15 labels who know what it means to be green.

 

1. Bario Neal

Just in time for Earth Day, ethical and sustainable jewelry brand Bario Neal has released six stunning new styles of engagement rings with responsibly sourced gemstones.

 

2. Allbirds

It has been said that these are the comfiest sneakers, ever. It just so happens they're sustainably made, too. Plus, the brand meets stringent standards for the production of its super-soft merino-wool kicks.

 

3. A Peace Treaty

This is one of those brands that has been devoted to high fashion and sustainable production way before being eco-friendly was "cool." For luxurious, handmade pieces that truly stand out from the crowd, it's all you need.

 

4. Bkr
Bkr's water bottles are BPA- and phthalate-free, and made from 100% recyclable materials — plus, each glass bottle has a silicone sleeve in colors inspired by the latest runway trends. Hydration in style? Sign us up.

 

5. Melissa Joy Manning
Admittedly a go-to for us when it comes to eco-friendly jewelry, Melissa Joy Manning's innovative designs feature antique charms, upcycled stones, and other ethically sourced materials that make her stand out in a sea of baubles.

 

6. Baserange

 

Utilizing high-quality bamboo fibers, this minimalist loungewear and intimates line makes clean, cool basics for the fashion crowd.

 

7. Heidi Merrick

 

 

Who says responsibly produced clothing can't be chic? Made in the heart of Los Angeles, this on-trend independent label proves that it totally can.

 

8. Master & Dynamic

For Earth Day, Master & Dynamic is offering its flagship models in Alcantara, an eco- and vegan-friendly luxury material (an alternative to leather) made in Italy. And, they look damn good, too.

 

9. Vitamin A Swim

Another brand that proves sustainability can be sexy, Vitamin A was the first swimwear brand to utilize recycled fabrics made from recycled nylon fiber and plastic bottles.

 

10. Elise Ballegeer

For architectural takes on wardrobe essentials that use organic and sustainable materials, look no further than Elise Ballegeer's selection of eco-conscious pieces.

 

11. Colico 

When you buy a pair of shoes from Colico, you know you're buying a thoughtfully made product that will actually last. The brand uses water-based glues, makes heels without plastic fillers, and boasts totally carbon-neutral production practices.

 

12. SVILU

Forget the trends — this brand creates modern-yet-timeless and trend-transcending clothing with mindful sourcing and local production. Plus, it's always researching new ways to reduce its impact while still providing modern staples.

 

13. Hackwith Design House

We always turn to Garmentory for tons of indie, sustainable brands all in one place, and for Earth Day, the site's teamed up with Hackwith Design House on an exclusive LBD made of 100% tencel, by hand in Minnesota.

 

14. Giejo

Earth Day falls right at the start of swimsuit-shopping season, so check out this fashion-girl approved, made-in-NYC swim brand ASAP.

 

15. Gräf & Lantz

Before you buy another plain black tote bag, consider scooping up one of this brand's colorful and honestly produced accessories. The designers were even inspired to minimize their footprint by utilizing the extra scraps of fabric to create fun extras, like coasters, wallets, key chains, and luggage tags.
