Has anyone tried periwing Chinese wedding dresses? does they look cheap or good?

Please help, my wedding is soon, and I am looking at dresses online. I saw many websites. I also checked this www.periwing.com Chinese wedding dressings. they looked good for such a cheap price, but has anyone tried them or bought from them before? because i am scared that the dress will look very cheap, or cheap material for a cheap price. Any advice? and thank you :)
