Answer 2

Clothes are washed with soap or detergent  solution .This solution is hypertonic as compared to osmotic concentration of our skin cells . The washing solution ,therefore ,result in exosmosis in the skin cells that come in contact with it for some time .Due to this reason, our hands get shrinked while washing clothes.
