In the officers' mess it is a long sleeved shirt with a tie. Imagine sugar or coffee plantation owners, (psychogically or socially) unable to chill out to any great degree, just removing their jacket during a function on a warm summer's evening. That's "planter's order".
UOTC - smart trousers and shoes, decent shirt with a collar, sleeves folded up just above the elbow, no tie.....
Supposedly what a planter could tolerate in a hot and humid evening in (say) Malaya - just smart enough. In particular I can't imagine too many real planters wearing a tie in 95F and 100% humidity.
But what to drink - Pimms might be common in the evening, a long G&T is the obvious answer, but not if the smell of juniper berries makes you sick. Some gins are light on juniper, but what's the choice...........
You might not be able to imagine a planter in a tie in 95F/100% humidity. However that is exactly what they did wear. Shirt sleeves were not rolled up because of insect bites. I have this on the good authority of my late great-uncle who was in Malaya from 1935-1940 and 1946-1954
Yes, I should explain it was my referring to dressing in planters' order whilst on exercise in Belize, that led to the old fellah and I discussing his experience. We probably would not have turned to the delightful topic of sartorialness otherwise. We would instead have limited our conversation to a desultory question about "what I was planning to do with my life rather than messing around in the Army" as he charmingly put it!
When wearing a jacket, but not a tie, in Planters, we were required to wear open shirt collars outside and over the jacket collar. Definite need for a clean collar at this point.
Can only put that down to what some CO must have done at school, as that was exactly how it was at my school.
Somewhere still in the comfort zone therefore.
On the subject of cockle pickers, we took part in a quiz night in camp once a week whilst in Iraq. There was a prize for the best team name. One of the funniest - shouldn't have been, given the deaths involved - was "Morecambe Bay Cockle Pickers Second XI".
