It is an Alexander McQueen dress worn by Lady Gaga, the painting seems Renaissance, with an angel and another person/angel giving him a piece of parchment. I attached the best image I could find.

Also I'm trying to understand it and found your question. The dress is simply beautiful! And nobody speaks much about it, the web is only full of the meat dress. I'm not an art specialist but understand that it was Renaissance. I have googled for ours for renaissance paintings and found 'Saint Catherine' by Roger van der Weyden with nearly the same face and same colours of the one on the dress but it isn't it. Then I found this Blog http://standingcinema.wordpress.com/ of a mad for fashion girl who loves McQueen and finally some concrete results - scroll down to "Celebrate the New Dark Age", circa middle of the page - and the blogger did a really good work assembling the dresses near by the original paintings! McQueen worked with paintings from Hieronymus Bosch, Jean Fouquet, Stefan Lochner, Hugo van der Goes, Jan van Eyck and perhaps others, most northern Renaissance Masters. Much of them I had just "controlled", I bet much on van Eyck but it is... Stephan Lochner, Annunciation - Altar of Three Magi in Cologne Cathedral, ca. 1440. Oooh, a German artist, argh, my country, I will comfort me that he was a fellow of van Eyck and that you will be happy too to read this! Much greetings, Heidi

That is awesome! I thought it was a Germanic or Flemish artist but you found the exact one! Very nice job! Well done! I'm glad now that we have information about other things, not just the "meat dress".

All the best,

Oh! I have one more question! Do you know what is written on the paper the angel has? I think it's Latin, but I can't understand the words.

I have read much now about the painter, now I know also that Lochner followed as well van Weyden, the one I first thought the painting was from, good to know that not everything was wrong. And I read also about the Cathedral of Cologne where the drawing of the dress is. Did you know that there are reliques of the 3 magic kings? That they where the reason that the cathedral was built? And that the cathedral was since 1884 the highest monument of the world, before Washington Monument and then Eiffel Tower? And that "our" picture is on the outside on 2 movable wings of an altarpiece and that inside is another painting McQueen used? It is The Adoration of the 3 Magi, you can see the photo of the dress in the block I linked. The altar is the masterpiece of Lochner. New of this epoch is that Maria is now sitting in a room, not anymore outside in the nature or under a porticus, and she is reading and studying, so the cherub can bring her a written scroll she can read, lol, symbol of an official act between God and humans. Nice the details: the curtain, the slightly curved curtain rod, the damage on the door wall, the stonemason marks on the floor tiles, the jug with flowers and the inscription "ancilla domini" - Handmaid of the Lord, so everybody knows who she is, lol. And the open! (in pictures normally closed) scroll with the Latin words, what else can they be than: Ave gracia plena dominus tecum - Hail Mary full of grace the Lord is with thee, the famous traditional Christian prayer made of the words from Saint Luke's Gospel 1.28. Wow, how much things now we know beginning with a dress of Gaga.. – Ah, strange thing, both, Lochner and McQueen, died at 41 years. Greetings Heidi

I forgot, here you can see pictures of "our" Lochners painting in high resolution: http://kunst.gymszbad.de/kunstgeschichte/motivgeschichte/altaere/lochner-3koenig/lochner-koenig.htm
Click on the thumbnails you see there...

Thank you! Thank you! Thank you!

Now I understand a lot! Thank you for the link to the high-resolution image, you are awesome!

All the best,
Remus

Nice that you like it. If you see the latin words on the high resolution photo and don't recognize all the words like me, do not wonder, in this epoch they wrote Latin with abbreviations, you see: " .AVE GRACIA PLE" and then "NA DNS TECU ", it is a recognised shorthand for 'Ave Maria Gratia Plena Dominus Tecum'. The scroll has also a red seal, a nice symbol because only royal persons used a seal to validate the acts which were executed in their name, here the act is from God.

Have you seen this wonderful photos of Vanity Fair with Gaga and the dress?
There is a second one with a clickable thumbnail beneath

Very nice, thank you for sharing this! She is a real artist and you are truly an inspiring person, searching for all this - and finding it!

Here is a strange thing, but typical for Gaga loving her little monsters (lol): there is no Mary in the picture on her dress! The angel is mirrored, and it looks like the angel receives something from himself; or from another angel.
But the parchment he receives is the mirrored one, the reversed one. So, with her symbolism of monsters and other stuff like that she actually has a sort of anti-Annunciation on the dress. In many languages Annunciation can be translated as "good news", so on Gaga's dress there is a "bad news"?
Symbolism is so cool!

I added a picture to show the edits on the dress (the two angels)

Yeah, really curios that the image is reflected, I didn't see. And that's why nobody could read the letters there, lol
