easy slip on sandals, skirt, sleep wear, 1 pack of always supers, soft hand soap, water flavoring (if you don't like just water) couple packs of cotton undies, stuff for entertainment, that's about it off top of my head, make sure you have a good headset for the plain trip-seriously cant recommend this more, travel pillow. that's about it off top of my head.
Collectively I spent about 17k that included on medical tests before the trip, the hotel, food, water, everything including some shopping too. and when I got back I still needed help for survival which I got from some friends, and family so be sure to have enough for another month of living when you get back, and you should be good !!!
