Bought this but never ended up wearing it to an event - but its adorable! Size M SOLD OUT dets! Non-adjustable straps, mock neckline. Side ruching. This is a deadstock knit fabric made from 50% Nylon, 45% Metallic fibers, and 5% Spandex. Hand wash + dry flat. More on fabric & care. The Alden Knit Dress pairs well with the Medium Rosetta Shoulder Bag, and the Regan Knee Boot.
