Maternity innerwear with temperature regulation function, size M-L, black. - Brand: Rosemadame - Size: M-L - Material: 80% cotton, 15% rayon, 5% polyurethane - Bust size: 86-101cm - Abdominal size: 81-110cm Thank you for viewing. This innerwear is made of functional material that releases heat and retains warmth, and absorbs heat and cools, so you can stay comfortable in any season. I used the exact same one during my postpartum hospital stay, and it was convenient because it opened in the front and was easy to roll up the sleeves. I am selling a spare one that I haven't even opened.
