1) How often do you get to wash your clothes?
Response 1 - I washed some clothes at every hotel. Some hotels were very reasonable to send your clothing to be laundered. Others were very expensive. I sent mine out whenever I felt it was cheap enough or I was too tired to be bothered with it. Most of the time, many of us would wash our clothes in the shower and then lay them out on chairs, shower rods, hangers, etc., to dry. We were in hotels long enough that drying wasn't a real problem if we washed them the first day we were there.
Response 2 - I did mine frequently in the room and hung them out to dry. Some people sent theirs out.
Response 3 - You can get your clothing laundered at the hotels. The fee depends on the hotel. I washed undergarments in the hotel bathroom. I am not sure what your itinerary is, but we stayed in very nice hotels so I had no problem getting clothing washed. Just plan you budget accordingly.
2) Are short-sleeve t-shirts o.k. for women? Loose-fitting jeans?
Response 1 - Short sleeve t-shirts were fine. Most of us wore capri length pants. I would have found jeans to be extremely hot. Skirts were also nice and cool. Also, many of us purchased clothing there so that we would blend in with the crowds a bit better. Tunics were cool and reasonably priced.
Response 2 - all ok I liked a loose dress
Response 3 - Lightweight pants are best, no jeans, you will roast. Short sleeve t-shirts are fine as long as they look good. Heavy cotton is not advisable. I also had two part of travel pants from Chicos that were comfortable and did not wrinkle. Skirts are great too.
3) Should I bring clothes for "dressy" events? If so, how many of these events should I anticipate?
Response 1 - There are two "dressy" events to be prepared for. One is at the beginning in Delhi. The other is the banquet at the end. Many of the participants wore sari's for the final dinner, though I wore skirts and t-shirts for both.
