Hmm tough one... like choosing between the lottery numbers for Saturday or the ones for Wednesday, either way you win...
I am sure you know your partner the best, how about being fully shaved and sending him a text telling him a bit of what is waiting for him when he gets home, follow up with a bit more at 12, tit bits at 2, etc... By the time he gets home he will be so wound up by the anticipation he should be gagging for it.
Personally my other half looks great in most things, but her nurses tabard with nothing else (should be with trousers) always does it for me...
i was talking about barry and natalie from eastenders by the way!
