How should a gentleman or a lady dress in the bush? Well, lets start from the practical point of view.

DRESSED FOR BUSHWALKING
On your feet you need a pair of sturdy walking boots. Make sure you buy them big enough. The ones I had were just my size, which proved to break my toe-nails when I walked in tough terrain. Very unpleasant indeed.
   Some experienced bushwalkers use two layers of socks to avoid blisters. Needless to say, this is very hot in the outback. I used one layer of socks.
   Over the boots you use gaiters (boot covers) to protect the boots and the socks from various sticky vegetables (and occasionally mud) that the Australian outback is full of.
   If you walk in high grass, you can opt for long trousers to protect yourself from snakes. I invested in a pair of combi pants where the lower part of the pants can be unzipped for warm days.
   Shorts should have a lot of pockets for knifes, compasses etc.
   In order to avoid to scare small and furry animals, your abdomen should be covered. I never felt the urge to use anything but my everyday T-shirt.
   I'm sensitive to light, so sunglasses are a must for me.
   On your head you should wear a hat with brims. It protects your face and your neck from the sun. If you come across water, wet the hat in the water, this will cool off your head. I, like all the other overseas tourists, have an Akubra hat.
   The backpack is a model with fabric on the back, to reduce the sweat. Nylon backpacks make you stink. In the backpack, I carried my emergency equipment.
