Warm, you missed out the umbrella. True only required in the rainy season.
As we disembarked our wg cdr tore a strip off the WO that met us attired as you show so well. He also carried a brolly.
The WO said not a word, not one word. Moments later the storm broke. Without a word he erected the umbrella, put it over the wg cdr's head and escorted him to the bus.
Not another word was said about drress regs.
