This is the Cup Size Choir, seven angels in lingerie singing seven notes at your command. They lie down, breathing sensually, waiting for you, ready to play Deck the Halls or whatever Christmas carol you want.

At the end of the exquisitely filmed short you will be able to play the Cup Size Choir yourself, using the ASDFGHJ keys—which, coincidentally, is exactly the noise I made when I discovered this site, made by Italian lingerie company La Senza. You can even record your performance and send it to your mom.
