Fiji Fashion

I googled “How to fend off cannibals” because I’m going to Fiji next week and then I realized the cannibals live in Papua New Guinea. Totally different island. Sorry, Fiji, my bad. We’re cool, right?
“Do not wear hats while you are traveling in Fiji as this is regarded as a sign of disrespect.” I also may not touch anyone’s head and I may not wear anything that bares shoulders or legs. AND I’ve been told I might have to wear a muumuu to a reception thingy. A muumuu! I might as well borrow someone’s burqa. Do you have one?
