Alright then, let me attempt to revive it.
It's 30+ celsius here. Every damn day. 100% humidity. Or 95% humidity with sun (not sure which is worse). I grew up in cold, rainy climes. I worked most of my life in them.
What is the best way to deal with this tropical weather? Fit, materials, colours...
In addition to what others here have already advised you, I have learnt a few things after living in a humid, tropical climate for 6 years:
- Don't wear linen, it absorbs all the humidity and your sweat and you'll look like a beat-up cat in no time. Fresco wools are the way to go.
- Don't forget to wear an undershirt (100% cotton of course), to help soak up some of that sweat and leave you shirt look a bit more crisp.
- Wear no-show socks, forget the over the calf rule. Not as an iGent statement, but it does help to have a bit of a breeze around the ankles when walking around.

This is complete bullshit. But then, you knew that already.
