Unfortunately the dress size is not suitable and the tailoring of dress is not professional. When asked for return, the customer care suggest to alter it ourselves. The dress is of poor quality as well.
Fortunately, my Mom still had plenty of time to get another dress for the wedding.
Moral of the story is… if you are going to order online from a Chinese company. ALWAYS use a credit card and have the credit card company issue a chargeback if they don't let you return. Chargebacks also hurt the merchant's ability to accept credit cards if they get a lot of chargebacks from consumers.
