I've never noticed it until I saw the picture of Michelle that you posted, but I see that she is wearing a small bolero jacket over her dress. I knew that the original dress was sleeveless , but heretofore I thought she had modified it by actually adding sleeves to the design. It does seem however that Michelle's version has a larger amount of red above and below the black in the middle as well as a different neckline.
