I placed an order for 2 dresses. One came with stains, and the other did not fit properly.
When I tried to return them, they would not process the return unless I sent them a photo of myself wearing the dress and showing where it did not fit.
I found that profoundly offensive. Sending a photo of myself in an ill fitting dress online to China was not an acceptable proposition, so after a flurry of emails where they promised to do it without, then changed their minds, i just decided to take the loss just to avoid any more annoying interactions with them.
Be aware that a photo of yourself wearing the dress is a requisite for any returns.
I found the whole process uniquely annoying.
