I wore an Elle MacPherson black jersey nightie that's very stretchy and it looks like a dress. No bra, no knickers. Easy to hitch up when the ob needed to do an exam. I kept it on until the epidural I think but otherwise would have kept it on till the 'end'. Actually maybe I did wear it till the end. All a bit of a blur! Anyhow, I wear it now as a dress too and it always makes me smile.
