I didn't use this at all because my morning sickness was severe. It can be used from the middle of pregnancy to the final month. It has been stored at home. It gently supports and stabilizes the belly, making both mom and baby comfortable. The inner side uses pile fabric that touches the skin, so it feels great to wear! The curves are different at the top and bottom, so it fits snugly according to the size of your belly. The size is free size. It's easy to adjust with Velcro, so you can fasten it according to your size and physical condition, which is reassuring.
