Simple black dress with two add ons

All of these items are in like new condition with no stains or signs of wear. The simple black dress is soft and a bit stretchy. It is sleeveless with a single button on the back. I'm 5'6 and this dress comes to halfway between my knees and ankles. Note: It gives the size as XL I would say a 12/14. We are adding a lightweight, very soft white oversized sweater. We are also adding a brightly colored gauze type short sleeves over cover. It is a Susan Graver and says it is a L Because it has no front closure it could be easily sized up or down
