Hi Anonymous User,
Welcome to SaleHoo! :)
www.opeshop.com is a new site, a whoisdomain check Link hidden: Login to view shows that it was just created March of this year, 2011. I didn't find any review online nor ratings on any of their services. The celebrity dresses they offer will be copies, not bearing the designer brands for these original gowns worn by these celebrities. :)
The site displays credit cards icons, but the payment method they actually accept is Western Union. I strongly suggest that you stay away from this site and use other reliable suppliers for gowns and dresses. I have gathered a list of drop shippers below for you to consider. I filtered my search to those that can send internationally -
