This is a copy of another company.
They copy the dresses so they are "not eexactly like the one on the website" as they said to me hence my dress arrived with significant differences.
After days of correspondence through the website contact page they refused to let me send it back and refused a refund, after some pushing I managed to get a 40% value of the dress compensation.
Customer service (which doesn't seem to exist, just a person responding to emails) were unhelpful and deflected all of my references to their returns policy, even asking me if it was "fair" to give me the refund when they'd paid out materials and labour costs to make it!
It would seem that http://millybridal.en.alibaba.com is the real website. I corresponded with Alibaba customer services who were extremely helpful and professional, this is how I found out about the deception of the other website.
Go through a website that has full contact details and use a credit card as this gives you greater rights to getting your money back.
