I purchased this at Tomorrowland. It's a summer knit cardigan from DES PRES MATERIAL FROM EUROPE. The buttons are made of a shell-like material, and the fabric is mostly cotton instead of yarn, making it a cool and breezy material. You can wear it with a camisole underneath, or even just by itself. It would also look great in spring or autumn, layered over a fitted turtleneck. The sleeve seams are located around the upper arm, rather than the shoulder, which makes your figure look more flattering. When all the buttons are fastened, the design beautifully exposes the décolletage, and the neckline isn't tight. The buttons are a bit thick, and due to the material, they can be a little difficult to fasten, but there's no particular problem. It has a lot of stretch. The size is 1. I haven't worn it much, but I love the design, so I'm hesitant to sell it. Therefore, please refrain from price negotiations.
