I'm not usually a fan of online dress websites, mainly because I've never come across a company with a good enough looking outlet and quality of dresses. But I can safely say that TopWedding has won me over as a customer.
They stock a good amount of designer options, dresses with certain fabric types as well as details of the neckline, hemline, train, body shape, etc. They are obviously not a pop-up-shop like a good few out there. I mainly shop with PayPal, so whenever I see a shop supports it as a method, you know you're dealing with a professional outlet.
The dress I bought is fantastic -- the quality of material is top-notch. The image matched the product I received PERFECTLY, and all my friends are asking where I bought it from! I will definitely be shopping with them again! :)
