I just wore a sports bra I was so comfy but sweaty so less clothes as possible then I got into a nightie after then within 2 hours I had to shower again due to heavy blood loss so put pjs on then a tracksuit to come home in x
I recently bought a comfortable maternity bra which in thinking of wearing under a shirt as I'll probably take the shirt of for the actual labour for easy skin to skin as soon as baby comes out.
