I'm not really a PJ gal either but mum bought be a whole stack of cute flannel PJs to wear in hospital. My intentions were to only wear them at night as I had leggings and maternity tops to wear during the day. Just ended up staying in the PJs the whole time as they were so comfy. I felt a bit too exposed in the legging especially while wearing a giant surfboard maternity pad with a frozen water filled condom shoved in it LOL

Whatever you wear make sure the bottoms are a dark colour in case of accidents!
