Midi dresses are one of those classic wardrobe essentials that can take you from a picnic to a party in the warmer months. Here are our favourite sustainable midi dresses from 23 brands doing their part for people, the planet, and animals.

Sustainable midi dresses you’ll love

Forget those poorly-made polyester styles lining the shelves of the main street that will fall apart after a few wears; these are the gold standard of more ethical and sustainable midi dresses to meet your needs. Perfectly paired with a sleek sandal, a chunky heel, or a Chelsea boot, midis are versatile and flattering and can be easily dressed up or down for any occasion.

They typically fall between just below the knee to just above the ankles, great for highlighting longer legs. If you want to create the illusion of length, a maxi dress may be more your style. And if the “modesty” element doesn’t matter (like in the office or a place of worship), mini dresses are said to be flattering on all body types. But of course, wearing what makes you happy is the most important thing.

There’s something for every taste here, from the effortlessly feminine green A-line dress by TAMGA Designs (US) to the vintage-inspired red number from All the Wild Roses (Australia) to the romantic midi from BASTET NOIR (Macedonia). Let’s explore.
