Although it took quite a while for them to respond to my email request for refund (my dress did not fit), they did and did allow me to return the dress, although they stated the cost may be $40-$70 dollars since it is oversees shipping. THey also offered the option below, which I thought was nice, and that is what I am going to do. Hoping it works!
"So we suggest you donate your dress to GoodWill within 7 days and you will get an (after deducting the shipping fee we paid for the package) 70% refund with the receipt, we will refund you as soon as we get the receipt from GoodWill or any kind of proof of donation. Just send us the picture of the proof will be fine."
