At the risk of getting a reputation for being too serious (I already have that reputation here at home), I try to keep my shoes down to 3 or 4 on a trip like this. I know, I know, I'm a traitor to my gender, etc. etc.
But I will make a bet with whoever, that you will not wear half the stuff you bring, shoes or clothes. Even I, on my third trip, will end up not wearing some of the clothes that I am bringing, and I'm on for two weeks.
Oh, and my reef shoes don't count!
Now, on the subject of jewellery ...
