The weather can't seem to make its mind up these days? But you can! 

 

Be perfectly attired for every season – and every time of day.
 
Four seasons? They're becoming a thing of the past. You can be sweating buckets in March and freezing again in April.
And in the numerous transitional periods it's often cool in the morning but significantly warmer by midday. The solution is to opt for a layered look.
 
This is certainly not a new trend, but it's becoming more relevant than ever – and is perfect for business, particularly if you want to get away from the standard shirt / jumper / jacket / suit combination.
 
Now
 
A shirt with a trendy, understated minimalist print.
And on top, a waistcoat! Not too warm, not too cold. Not too formal, not too casual. Absolutely stylish.
 
In a word: perfect.
 
Later
 
When the sun comes out and the temperature starts to rise, the waistcoat comes off.

Chinos pick up on one of the colours in the shirt, and loafers or more formal shoes and matching belt stylishly round off the outfit.
 
Not too severe, but absolutely correct.
