It feels like a soft sweatshirt. I remember the product description mentioning it was a "cardboard knit." It has slits on both sides, making it easy to breastfeed, and can be worn from before pregnancy to after. It has been worn a few times, and there are no noticeable scratches or stains. ⭐︎ Color: Gray ⭐︎ Size: Marked M-L ⭐︎ Measurements (flat lay) Shoulder width: 31.5cm Body width: 50cm Front length: 55cm, the back is about 3cm longer than the front.
