Dear Gentlemen,

instead of wearing black suits all the time try to combine grey and dark blue!

It's looking elegant, but not stuffy and not too casual that you have to

 change your clothes before having a meeting.

The combination of grey and dark blue is the new black!

Especially in winter you could wear a grey suit and a dark blue woolen coat.

A great look for every day business!

Yours faithfully,

The Gentleman
