1. Just wear the same clothes for a week or so and then just throw them away.
2. Don't bring any clothes and buy from the used clothes store and give away when done with them.
3. Only go out every other day and run around the house naked half the time. That way your clothes would last two weeks...
4. Never go out and run around the house naked. Clothes you arrive with will be good to go when you depart.

Hope that helps.. keith
