So, I did a little digging. All the beautiful dresses sold for an extremely cheap price on this site are replicas of designer dresses. They pretend to be from England. They are not. ALERT! The pictures they use are of the original designer dresses! Not their replicas. They rip off the images of the original dresses from the designer's site. Example:
Bycouturier dress: https://www.bycouturier.com/low-vback-wedding-dress-g4445
Original: https://dimitrasbridal.com/gali-karten-bridal-collection-debut/
If you want a replica of a designer dress you can try them out. Some people want a low price tag. Just don't expect it to be exactly like the picture since the picture is stolen from the designer's site. I'm sure they'll try their best to replicate it though.
