Our 15 Favourite Sustainable Maxi Dresses

While hemlines have gone up and down throughout history thanks to trends and economic necessity, the current climate sees a lot of diversity in how long we wear our dresses. But one versatile style that has made a comeback in recent years is the maxi dress, coinciding with the viral Cottagecore aesthetic through lockdown that generally favours a more modest approach to dressing. Easy on its own for a casual vibe or accessorised for more formal occasions, and layerable with a big coat and boots in the colder months, the maxi dress is versatile and flattering on a lot of body types. Ideally it should hit around ankle length, and of course, sustainable maxi dresses are a given!

Whether you prefer a classic maxi dress like the one from LANIUS (Germany), an inclusively-sized boho option from Christy Dawn (US), or a Cherry red skivvy dress from A.BCH (Australia), we’ve got you covered all the way down.
