Shipping, returns & fit

Shipping is free on every U.S. order — no minimum. Orders are delivered within 1–2 business days, with tracking emailed on every order. We currently ship to U.S. addresses only.

Orders are picked and packed within 1–2 business days. Once shipped, delivery normally takes another 3–7 business days, and you'll receive a tracking link by email. Full details on our Shipping Policy.

You have 30 days from delivery to return any unworn item with tags in its original packaging. Return postage is paid by the buyer, unless your item arrived damaged, wrong, or never arrived — in those cases we replace it or refund you in full and cover the postage.

Approved refunds go back to your original payment method within 5–10 business days. See the full Refund Policy.

Dimensions for each piece are listed in the product description above. Because many pieces are handcrafted, slight variation in shape and shade is normal — that is the craft, not a defect.
