Cap-sleeve, Fit-and-Flare Midi Dress.

Design & Construction
Fabric: Most versions of this designer dress are crafted from Mikado. This is a heavyweight silk blend with a subtle, luxurious sheen that is stiffer than standard satin, allowing it to hold "architectural" shapes like the full, pleated skirt seen in the image.
Bodice: Features a V-neckline and short cap sleeves. The tailored bodice typically includes figure-defining seams that transition into sharp, volume-adding pleats at the waist.
Skirt: A voluminous A-line skirt that usually features hidden side-seam pockets, a practical yet elegant detail common in Badgley Mischka designs.
Closure: A concealed back zipper ensures a smooth, seamless fit through the torso.
