Our story

What is the cost of fashion?

The detrimental effects of fast fashion on the environment are well cited. Pollution, excess waste, water consumption...

Yet what a travesty it would be if the world prohibited the diversity and creativity of fashion. Self‑expression is an act to be celebrated.

To bridge the gap.

We believe a love for quality fashion and a respect for our environment can co‑exist. We aim to enable a circular economy of high‑quality items, where each item that has been loved before can be loved again by another. Let's do our part and buy secondhand when we can. We'll do our best to help.

Find deals on pre‑loved items as you shop.
