It's hard to recommend a wedding dress store without knowing your preferences. When I was preparing for my wedding, I ordered here
https://www.thebridallounge.com.au/ - there I found exactly the dress I had been dreaming about for so long! Long to the floor, with a beautiful train and a bust embroidered with stones. Very beautiful! I bought it online, with free shipping, and then asked the seamstress to fit it to me.
