Many places recommend Ziploc bags labeled with your name if you must bring anything at all.
Also, been mentioned before, but worth mentioning (many times over)...if you do choose a skirt NO THONGS! There is a possibility that either you will be sitting on the floor, or you will be sitting in a chair with a sister sitting on the floor in front of you. They don't want to know what your Brazilian looks like, no matter how cool it is...I promise.
