Completely naked - I have started off both times in an oversized T-shirt and the first thing to go was my underwear because I was in too much pain to lift my legs to keep putting them on and taking them off (I was in and out of the shower for a lot of my labours). At some stage I lost the oversize t-shirt and ended up naked.

The midwives did talk about partners and showers/baths in our birth classes and said that they want them wearing shorts/boardies at least. We never packed anything special for DH - he just helped me through in whatever he was wearing, though I always have packed a spare change of clothes for him after labour is over just in case he ends up wet or covered in lots of blood and stuff. He can stay at the hospital for as long as I need him to without going home to change.
