Tight-fitting clothes in 90-degree weather? No, thanks—we can feel the sweat pooling already.

We’re all about easy, breezy basics this summer, like slip dresses that can be quickly dressed up or down with a quick change of shoes, accessories, or layers. We’ve narrowed down our favorites to the seven brands below, designed with lightweight and breathable fabrics like linen and silk—which are responsibly sourced, to boot. Don’t just survive the heat this summer, thrive in style. 😎

Don’t miss sustainable sandals or summer hats to complete your wardrobe.

1. MATE the Label

Sustainable Materials | Linen
Sizes | XS-3X
Price | $148

MATE the Label’s Linen Slip Dress is “flowy and form-fitting all at once,” so it’s the perfect dress to drape over any size curves. Available in sizes XS through 3X in three neutral colors (and one limited-edition one, in dreamy basil), it’s definitely a warm-weather staple for most. (The team even updated the adjustable straps to be more comfortable after gathering customer feedback!) All dresses are made in India by artisan women, and the linen fabric uses less water and carbon throughout the production process. 

2. Quince

Sustainable Materials | Mulberry silk
Sizes | XS-XL
Price | $80

Quince makes effortless basics at affordable price points, and the 100% Washable Silk Slip Dress is a must-have in our summer capsule wardrobe. There are eight colors to pick from, from a beautiful forest green to pearlescent champagne—all made with washable mulberry silk with a satin sheen. This piece will hug your curves and hit just around the knee, making it an immediate go-to for date night. The silk meets OEKO-TEX and Bluesign standards and will last for years to come.

3. Outerknown

Sustainable Materials | Cupro & Tencel
Sizes | XS-XL
Price | $168

Sun’s out, slit’s out! Outerknown’s Ellison Slip Dress comes with a single side slit for a certain je nais se quois 😉. The brand sources the Tencel from sustainably harvested eucalyptus trees and the Cupro is made from regenerated cellulose derived from cotton waste, aka an eco-friendly fashionista’s dream. The colors here scream fun and bold, ranging from bright magenta to an ombre saffron gold. Wear this slip dress on your next beach day, while you’re running errands, or at an upcoming work event (paired with an office-friendly blazer, of course).

4. Neu Nomads

Sustainable Materials | Tencel modal
Sizes | XS-XL
Price | $199

Launched by two best friends in New York and New Delhi, Neu Nomads focuses on simple, sustainable luxury with a clean supply chain. Made ethically by women in India, Nepal, and Portugal, and with a focus on renewable materials and zero-waste packaging, these beautiful pieces are worth the investment. The Easy Slip Dress is available in 15—yes, 15!—shades from crimson to plum to lapis to olive night, all dyed with nontoxic AZO-free pigments. Plus, it’s lightweight and soft thanks to the Tencel fabric. Get one (or three, we won’t judge) and slip into something simple yet stunning day after day.

5. Boody

Sustainable Materials | Viscose bamboo, organic cotton
Sizes | XS-XL
Price | $37-$70

Whether for sleep or summer style, Boody has three different kinds of slip dresses to choose from. There’s the Goodnight Slip Dress that’s breathable and light, perfect for getting your best night’s sleep. Or, you can go for the Everyday Slip Dress as a layering essential—available in two colors, black or nude, and designed to hit mid-thigh. Or, finally, you could try a maxi-length V Neck Slip Dress that can be dressed up or down. Whichever you choose, you can rest easy knowing they’re all ethically and sustainably produced using FSC-certified and OEKO-TEX certified bamboo. 

6. Cuyana

Sustainable Materials | Silk
Sizes | XS-XL
Price | $228

For a sexy and slinky slip dress, we recommend Cuyana. Made from Crepe de Chine silk in China, these pieces are gorgeously designed with a V-neck, silk band, and A-line shape. Just throw on a light jacket or add a sweater on top and your look is complete—whether for a romantic dinner or out on the town with friends! Cuyana’s pieces are Bluesign certified so they’re both sustainable and safely produced. Choose from the “Core” black option or the equally sultry and deeply rich Poppy, Mushroom, or Dark Rust colors.

7. Bed Threads

Sustainable Materials | French flax linen
Sizes | S-3XL
Price | $80

Sometimes, we just wanna lounge! Bed Threads’ linen slip dresses are our favorites for functional yet easygoing pieces that we can rest around in. They’re made from 100 percent OEKO-TEX certified flax linen and are heavy-duty enough to be durable but light enough to stay cool and comfortable. Plus, we love the sizing that goes up to 3XL, the thoughtful details like adjustable straps, and the dazzling array of colors from pink clay to mineral blue to subtle pinstripes. Bed Threads is entirely carbon-neutral, too.
