Mystery Dress

Today I leave you, reader, with one image of one dress with magnificent style. I regret that I do not know the designer or the photographer or even the model, but I can promise you that couture-loving larks in forests everywhere are singing with delight at this masterpiece, regardless of the origin. 

Anyone who can discover the designer or collection to which this dress belongs: I will give you one quiddelpip of laughter and two perfect pinches of diorushimin!
