There's absolutely no doubt about it but it is cruel to want women to wear nylon stockings in the summer. Here in Queensland Australia the days are hot around 30degrees Celsius every day which is nice but you really have to dress accordingly or you could die from heat exhaustion. No joke!
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.
