Nylon is a man made material from the petrochemical industry and nylon doesn't 'breathe'. It tends to cling very tightly to a woman's legs and the crutch even with a cotton gusset becomes over-heated so yeast infections are rampant due the hot and humid summer days. This is a very uncomfortable condition for women. But luckily most Queensland women have adapted a very common sense approach to dealing with this problem.
Unless you absolutely, positively, "can't-get-out-of-it-except-by-dying" have to wear stockings during the day time, you simply make sure you have a nice pedicure for your toe-nails and an attractive loosely fitting dressy outfit and go off to work. Coolness and comfort are the requirements of living well in a tropical environment.
However, if you are an office worker sitting at a desk all day in air-conditioning you need to always make sure you have a cardigan handy in case you start to get too cool because someone coming in from outside has turned the thermostat on the air-conditioning down too low.
In an office environment this is quite a common happening and if you are too scantily clad you can get ill. As strange as it may sound to anyone who has never lived in the tropics, I have caught pneumonia from just such a scenario. I once used to do a lot of field and lab work with wild animals and I had to come into the library for morning tea, lunch and afternoon tea if I was working around the laboratory. My clothes would be wringing wet and sitting in a super cool environment that the books needed to discourage the growth of mould, I became quite ill. So, just to be on the safe side just make sure you have a cardigan or jumper handy to put on.
If you live in the tropics you really don't need to wear stockings unless you go out somewhere special at night.
