Orders are prepared within 1–2 business days. After dispatch, delivery takes 2–4 business days in the United States and 5–9 business days across Europe.

These are estimates rather than guarantees. Customs checks and peak periods can add a few days.

Shipping is calculated at checkout from your address and the size of your order. You see the exact amount before you confirm payment, and nothing is added afterwards.

Customs duties and import taxes, when they apply, are set by the destination country.

Each product page lists the sizes available for that specific piece, and our size chart converts between US, UK and EU.

If you are between sizes, write to us with the piece you are looking at and your usual size and we will tell you which one to take.

You can request a return within 30 days of delivery. Items need to be unworn, in original condition, with the tags still attached.

Write to us before sending anything back so we can issue return instructions. Once your return arrives and passes inspection we refund your original payment method.

Checkout runs on Shopify's encrypted, PCI-compliant infrastructure. We never see or store your card details.

The payment methods available for your country are shown at checkout.

As soon as your parcel leaves the warehouse you receive an e-mail with a tracking number and a link.

If 48 hours have passed since that e-mail and the tracking has not moved, contact us and we will follow up with the carrier for you.

If your order has not been dispatched, we can usually change the size, correct the address or cancel it. Send us your order number as quickly as you can.

Once a parcel is with the carrier we can no longer modify it, and from that point the route is a return.
