New, unused set. The one-piece dress is made of stretchy, smooth material. It's sleeveless, so layering with a cardigan or jacket will make your shoulders and arms look sleek. It would also be easy to match if you changed the outerwear to something else, like red. The cardigan is thick. It's glamorous with beads, so it would be great for Christmas parties, reunions, etc. The sleeves have a cute design. The size is listed as M, but it's a large fit and the fabric is stretchy, so I think an L would also be okay. If you change the outerwear to something thinner, it can be worn all seasons. Please feel free to ask any questions. ◆ Cardigan Color: Gray Pattern/Design: Solid, beads, buttons Sleeve Length: Three-quarter sleeves ◆ Sleeveless Long One-Piece Dress Color: Black Pattern/Design: Solid, stretchy Season: Spring, Summer, Autumn, Winter #SetCoord #TopAndBottomSet #Party #Formal #SleevelessOnePiece #LongOnePiece #OnePiece #Cardigan #Beads #Jacket #Christmas #Halloween #Party #Wedding #Dress
