The beauty of Trouva is that your product(s) will be shipped to you directly from the individual boutique(s) you shop from. Therefore they will be sent from the country that the boutique is based. You can see where your boutique is based when you place your order and on each item listing on the right-hand side underneath the item's title.
Please be aware that you are responsible for paying any customs and duties charges incurred in the delivery of your order.
Additionally, if returning your order, you would need to send it back to the store it was sent from.
