|Florence + the Machine, MTV's Unplugged, December 2011.|
I could not find any identifying information for who designed the dress but after some research (perhaps too much time was devoted to this task...) I believe this dress to be a Valentino from the 2011 collections, because 1) Florence has worn Valentino before and had attended the 2011 Pre-fall collection as an invited guest and 2) the style and coloring matches that of items within that same Valentino collection. I hate the fact that I can't find any confirmation of this. Almost all of her other performance outfits are sourced somewhere on the Web but not this one. Arggh. Why is there no "What Florence Wore" site when there is one for Emma from Glee?
This is the only picture I could find to get an idea of the skirt's sweep. It reveals a slight train in the back with the fullness flowing down from a form-fitting silhouette at waist and hips.
This picture reveals how the sleeves seem to be ruched at the top, perhaps even smocked at the shoulder, resembling epaulets which is reminiscent of the 1940s military-influenced styles. The bodice is then fashioned with a simple bateau neckline.
