I too wore what i popped on at the time that felt comfy and nothing underneath ....

My labour/birth outfit was hilarious it was a bright Aqua T.Shirt nightie with a picture of a cartoon character of a sexy gangster woman pointing a huge machine gun with the words written above " Secret Agent 66 "

My sister had given it to me years before as a gift as i was born in the year '66

I found out later my midwives were laughing about it.

I have kept the nightie to give to my DD when older even though it's now a bit shabby but i reckon she will get a laugh out of what i wore when she came into the world and that she laid on it straight after birth !!!
