Maggy London cocktail dress

Received in a Stitch Fix. Worn a couple of times to different formal events - still in great condition, but it's much too tight on me now! Size is 6, brand is Maggy London, bateau neckline, short cap-sleeves, short but modest hemline (falls just above the knee to mid thigh), colors are white black and blue with intricate pattern, material is thick stretchy and comfortable, small zipper closure up the side for easy fit.
