As can be seen here everybody has different thoughts on what to wear.
For me I start at the bottom and work up. Shoes, inmho you Can't beat Simms Flats Sneakers. Expensive compaired to cheap neoprean booties but worth the extra, you only have one pair of feet and neoprene dosen't stand up to coral. Socks the best I've found is to wear a pair of Sealskin sockets under a pair of Simms Wet Wading Socks or on their own when on the skiff. Trousers Lightweight Regatta or Craghopper cheaper than flats either zip off legs or not. Shirts again lightweight designed for the tropics regatta are cheap and good. a hat for your head any with a peak ie baseball cap will do
Sunglasses get the best you can afford Costa, Action Optics, Haber to name 3.
Finally if like me you suffer from cold sores dont forget to take your Zovirax along with the sunblock lip barm the hot sun will affect your lips I talk from experance I had a trip to Cuba ruined because I forgot mine, along with what ever sun screen you want,
Have a good trip and enjoy.
