We believe the fact the dress was worn at one of the most talked about weddings of the year was only part of the reason it was so widely shared.
The other reason is that it is stunning.
The dress combines a low cut back with the long lace sleeves made popular by the Duchess of Cambridge's Sarah Burton designed McQueen gown and seen on the wedding dresses worn by Geri Halliwell and Emily MacDonagh.
It was designed by Israel-based designer Dimitrius Dahlia Haute Couture. The designer's current collection can be found in shops in Dublin, Ireland and Athens, Greece. The dress is from the fashion house's 2014 collection.
An imitation design is currently available to buy (in sizes 6 to 20) from online retailer AliExpress for just £133.52, plus £10.68 shipping.
We think another Dimitrius Dalia wedding dress shot could easily end up as a case of viral mistaken identity. Does this model remind you of anyone?
Here are some more beautifully dramatic designs from Dimitrius Dalia:
