Just me maybe but I prefer the cabin to be cooler not warmer - lets say 22oC / 23oC. I can cover up, grab a blanket if chilly but for the sake of others in the cabin I don't think getting naked is the solution to feeling too hot and stuffy.
However I sympathize; many Asian mates who have been used to hot and humid temperatures since the day they were born and who have BMI figures that near zero freeze up & hibernate if the temperature goes below 25.
