Mixed-media ballet-sleeved formal with satiny details by Beside Couture Add a dash of glamor to your upscale event with this mixed media evening gown by Beside Couture. A savvy square neckline sets a fashion-forward precedent at the bodice, and slender translucent sleeves sluice to satiny split cuffs at ballet-length. The trim design details a curvy fit along the sheer-layered bodice and upper skirt, while a satiny contrast details the lower skirt and fluttery full-length.
