Sleeveless Unitard Maternity Jumpsuit This unitard is very comfortable to sleep in. Super light material and it doesn’t ride up like most unitards tend to do. I found this to be extra comfortable at night or when walking around doing housework. This is listed as M but I was in between M and L before starting pregnancy and it fit just fine. If you are concerned I would go with the size chart provided by the brand. If you have any questions please leave a comment 🙂
