Once the check out process has been completed, changes to the order in terms of item/size/color/quantity can no longer be made. Below are your options: 

a. Proceed the order and request return-exchange upon checkout but since our stocks sell-out quite fast, we cannot guarantee the availability of the item(s) as stocks may vary per boutique.  

b. Request for cancellation and place a new order. Your refund will be automatically processed. The amount will reflect based on the payment provider's processing leadtime.
