I don't know much about fashion, but I know what I like. And I like what I recently saw in a 44-year-old ad for King Gee Permanent Press Tropical Shorts (posted by the brilliant Facebook page, Lost Melbourne).

1970 was a different time. I was minus 12 years old back then, so my memory of the era is a bit sketchy, but the ad tells us this was a time when 60-year-old men in exposed knee-high white socks consulted blueprints while standing. A time when the word "Bermuda" meant something so much more than "tax haven". A time when some hastily scribbled red texta sufficed as the background for a print advertisement.

It was a different time, a time that we should look back on with nostalgic envy.

The question of whether or not to wear shorts in a corporate environment is barely worth asking. Of course you should. The more pertinent question is "Should I wear a shirt and tie with my shorts?" 1970 tells us that the answer is yes. The shirt can be long or short-sleeved, a pocket holding a pen is preferable and the tie-knot should be no bigger than a 5¢ piece. The shorts' hem should end well above the knee.

The ad is silent on whether this uniform is as appropriate for men as it is for women, so I'm going to make an executive decision and say it most certainly is.

There's your guide to warm weather workwear, Benign to Fivers. No room for interpretation. Go to it.
