Between sizes? We recommend sizing up — a little room to grow keeps a keepsake wearable longer.

U.S. shipping is a flat $50 per order, and free on orders over $800. Every order ships from our fulfillment warehouse in Hong Kong — prepared within 3 business days, then delivered in 2–7 business days with FedEx tracking — estimated delivery Sep 22 – Sep 29.

Because every order travels with FedEx, we need a full street address — FedEx cannot deliver to PO boxes or APO/FPO addresses.

Unused and unworn items may be returned within 30 days of delivery. We provide a prepaid U.S. return label and charge no restocking fee. See our Returns & Refunds policy for the earrings hygiene exception and instructions.
