There can be three considerations that can be taken for this:
If the item runs out of stock, it would be labeled the same and the item won't get added to your shopping bag. However, if the item goes out of stock after it has been added to your shopping bag but before your check out is completed, you will be informed at the time of check out.
Such items can be added to your wishlist and we would try our best to contact our boutique and provide you with your wishlist item at the earliest possible. As soon as your wishlist item will be available with our store, we will notify you for the same so that you can place your order.
If an item goes out of stock after you have placed your order and received an order- confirmation, then, we will try our best to fulfill the order by sourcing the selected item. In the event that we are unable to source it for you, or if it is likely to take more than 15 days to ship, we will inform you about the delay and cancel the item as per your convenience and reverse any charges made to your credit / debit card against that item.
