Why Alternity

We change shape. Our clothes should too.

Through pregnancy, life and time — our bodies change, and an enormous amount of clothing is wasted because of it. Alternity makes garments that adapt instead of being replaced, so you can love your body and your wardrobe at every stage.

🌳We plant a tree for every Alternity item sold, in partnership with Just One Tree.

Zip Us In Heritage

Before Alternity, there was Zip Us In.

Our award-winning jacket expander panels — featured on Dragons' Den — started it all. One panel turns your existing coat into a maternity jacket and a babywearing jacket. We're releasing the final heritage stock as a celebrated collection. Once it's gone, it's gone.
