Wardrobe under the weather

WHAT not to wear has been a choice subject this week. I've opted for the tie and the jacket.
Yes, the hot weather arrives, and it is not just those on the beach that are stripping off.
And so the question arises.... what is deemed business-like yet at ease with the conditions? Remember, it all comes under health and safety at work now!
Women seem to get it slightly easier, the dress code has never really been set in stone anyway. Smart summer dresses easily replace skirt or trouser suits, and arms completely disappear from tops, yet an air of professionalism remains
For men there are short sleeves, but for me, a collar should stay. As too should trousers. Talk of smart shorts worries me - as it leaves a nasty question mark over footwear - and never in the office should a flip flop / open toe sandal be sighted!
Also, cotton shirts and trousers are often made from some of the lightest material you will find, far thinner than t-shirts.
Unfortunately it just means there's no let up from the dreaded iron - and that has to be the worst aspect of it all!
Ties have always been an issue, but with a smart shirt and jacket are they ever really necessary? They've been blamed for MRSA outbreaks, others feel they are down-right uncomfortable, yet they do pull a suit together.... but I may hold off while the sun beats down, just don't think I'm complaining.
