When you come out of the showering there are water droplets clinging to your body. These droplets of water clinging onto the body evaporate. For this water to evaporate it needs to absorb heat. Water absorbs this heat from your body. Also, the heat needed for water to evaporate is high. So, lot of heat is absorbed from the body. As heat leaves your body you feel cold.
