This is one of my favorite dresses. It's clean, simple, elegant, and very pretty!
Front View (Close-up): The gathering along the bodice seems to be fanned out. The fabric also appears to have a glossy spotted pattern to it.
Front View/Side View: Here is a fuller view of the front. Along the skirt, it seems that the pattern has lines running up and down. Perhaps the lines are made out of the glossy spots?
Back View: Instead of gathered, the back part of the skirt appears to be pleated.
Front Full View: It's hard to tell in this picture, but in the video it looks like the dress is made up of a cream colored overlay and a lighter colored (almost white?) underskirt. There appears to be a little bit of a pattern at the bottom of the overlay.
