The shipment of your product is our highest priority and everyday we dispatch hundreds of products to satisfied customers across the world. However, because the majority of our warehouses are China-based, our shipping and handling times can vary and we are therefore unable to offer next day delivery.

Processing time: As soon as we receive your payment, we immediately dispatch your order to our suppliers for order verification, tailoring, quality check and packaging which can take an additional 1-4 days.

Shipping time: This refers to the time it takes for items to be shipped from our warehouse to the destination. For US & Canada the deliveries typically take 7-15 days, United Kingdom 5-10 days, Australia 6-12 days, France 6-12 days, Italy 7-15 days.

For other international deliveries the shipping time may vary.

Tracking: As soon as your order is shipped, you will receive a confirmation email containing a tracking number allowing you to easily locate your product directly from our website at any time . Please note that while the majority of our shipping companies provide a tracking service, we cannot guarantee it in all cases.
