By Chere Di Boscio
Shorts? A bit casual. Jeans? Too hot. What I want to wear in the summer is a dress! And no one does them better than Reformation.
With an entourage of famous fans, such as J.Lo, Emily Ratajowski, Hailey Bieber and Meghan Markle, the U.S. based brand now has a huge following thanks to their plethora of stunning dresses, which seemingly never go out of style.
And of course, their dresses are sustainable, too!
That’s true in all kinds of different ways.
For one, they use eco-friendly fabrics, like TENCEL, organic cotton, and linen. But that’s not all! They also use deadstock, and sustainably sourced viscose. Not sure how sustainable a material is? No worries. They give all the details on each product page on their site. They’ll also tell you how much CO2 that material has saved compared to ‘conventional’ clothing and how to care for the fabric. The company aims to be carbon neutral and fully circular by 2030, too.
If you’ve logged onto the Reformation site and felt overwhelmed by the volume of choices, don’t worry. Here, I’ve rounded up 12 of the best dresses that are made to make you look and feel fabulous. They’re versatile enough that they can be worn to summer picnics, cocktail parties and even weddings.
These sustainable and ethical Reformation summer dresses will help you keep cool with their lightweight fabrics. Plus, you’ll feel like a million dollars wearing them, too!

We love the 70s vibes exuded by this gorgeous denim midi! But that’s not all. It’s oh-so-flexible, too. How so?
