It's a complete dead-ringer for Grace Kelly's wedding dress when she married the prince of Monaco! It's such a timeless wedding dress and better than any of the beautiful modern wedding dresses that brides wear nowadays. It's like a fairytale for the real world and I absolutely ADORE it! Jennifer Morrison could probably even play Grace Kelly based off this picture (Although Lily James looks more like Grace). She looks absolutely GORGEOUS and despite all the rants from the Swan Queen fans, I think this is the best wedding dress on the show. It's a mix of real world and fantasy, especially since it looks like the wedding dress that Grace Kelly wore when she went from an actress to a princess. Grace's dress is still beloved today and considered the most beautiful wedding dress of all time (as well as Grace being considered one of the most beautiful women that ever lived), so I don't get the problem people have with Emma's dress. I was hoping for a more swan-themed wedding dress, but it would likely be too fantasy for Emma's taste. This is a perfect blend of real world and fantasy, just like Emma. Such a beautiful dress for such a beautiful woman!

It's not a secret it's a copy of Grace Kelly's dress, JMO confirmed that herself in one of the latest interviews.
PS. didn't find the interview, but here's Jen's instagram link

That's where they said they got their inspiration from. ;)

It's an exact replica!

By the way, have you guys seen the comments on YouTube and Facebook? Idiots actually find this dress ugly.

Blatant rip-off right down to the bouquet!

P.S. Perfect for Grace Kelly BUT (Shipping Goggles OFF) so unlike Emma Swan's character.
