I originally thought I would be in the bath when in labour with my ds so I took along my swimmers (a two piece for easy removal), didn't like the sensation of the bath (or the swimmers on my body) so I ended up in the shower for 5 hours starkers! I honestly didn't even think or care who might see me naked and I usually am a huge prude when it comes to my own nakedness I would take along your swimmers and see how you feel during labour. don't forget a change of clothes for dh too as we forgot and my dh had wet clothes for the duration of our birth.. oops
