Just put on one item, and your outfit is complete. That's one of the many reasons we love the Sia jumpsuit. Besides that, it looks amazing with its V-neck and (optional) cinched waist. This might just be your new favourite summer jumpsuit because it's made of a nice, airy material: a linen and organic cotton blend.

The small buttons on the top are made of coconuts. Coconut shells are generally a waste byproduct of the food industry, so turning them into buttons is a sustainable solution we love.

We want you to have the perfect size in one go! Not sure in which size to buy the jumpsuit? Use our size tool by clicking the ‘What is my size?’ button. You can find the button under ‘Choose your size’ on the product page.

Our model is 1.70 metres tall and is wearing size S.

58% Organic cotton
