From the Universal Studio's film, "Snow White & the Huntsman", this is the Snow White Costume.

The dress is made of a dark green crinkle velour in the Renaissance styling, with open stripes of fabric for the puffed upper sleeve.
 It has a light blue gauze inset, and laced inner sleeves.
Just as in the movie, the dress is made to look tattered at the bottom, and the right outer sleeve was eliminated.
The outfit comes with dark brown velour leggings.
