There were a few combinations that shouldn't be worn together as per the original instructions .... but hell, one of those looks nice and trendy and thus is my favoured combination, weather permitting !
Unlike Colin, I don't seem to wear the same combinations that he does ... mind you, I'm usually cold and usually at odds with the majority of drivers in what I wear !
On a very warm day with a reasonably warm evening in prospect ...
Polo Shirt and waistcoat
most warm days
Polo shirt and Suit Jacket
add a shower
Polo Shirt and leightweight annorak
cool things a bit
Long sleeve proper shirt, tie and suit jacket
add rain
Long sleeve proper shirt, tie and leightweight annorak
cool things more
Long sleeve proper shirt, tie and fleece
add rain
Long sleeve proper shirt, tie and parker
cool more
add sleeveless pullover (tank top) (to Long sleeve shirt, tie, fleece (dry) or parker (rain) )
cool more
add jumper to the above !!
very ocassionally I'll wear the beanie hat, but only whilst walking in depots in the rain. I don't wear the formal hat. Shorts I'll wear in exceptional heat, say 29 degrees plus !
That covers most occassions ..... ever wish you hadn't asked !!
