See-through dress

It is very hot here (well, hot for where we live) and we have no air conditioning. Tonight, my girls really wanted me to perform a song for their dad with them. We had just come back from the pool, and I had taken off my suit and just put on a very light sundress with nothing underneath, since I was so miserably hot. I agreed to do the song with them and jokingly said, "Am I dressed appropriately?" to which my daughter quickly replied, "As long as you don't show your vagina."
I went and put on some underwear, just in case.
