Can share one idea that worked well. I pretended in the morning that I will come late from work and asked him to come by 4 to take care of our daughter. I dropped our daughter at a friend's place, came home and got ready. By the time he opened the door, I sat in the hall without saree just on blouse and petticoat with loose hair. For some reason, my hubby is super favorite of this getup. He got very excited, we had 3 hours of great fun and he said this is one of the best gifts he could have on anniversary. Just try it.
