As a woman's body changes during pregnancy, she eventually must buy maternity clothes, whose useful life is short. COAT+° is a coat that is suitable for pre-pregnancy, pregnancy and after delivery. It can be reconfigured to suit the gradually changing body shape of women as they advance through their pregnancy. After the baby is born, COAT+° can be reconfigured again. For women with limited financial means, there is no need to buy a coat specifically for pregnancy.
