If you need boardroom look... (basically dressy)... Outlier is hard to beat. (I am wearing one today... ) Pricey but not too much more than pair of nice dress pants.
I have one for So Cal winter, and another one in transit for 3 other seasons... (well actually... 1 ... summer).
Great to have when you have high profile meeting in conjunction with merino dress shirt.

Typically... it would be knickers for me from ATD/Cutter/Prana... I am really liking ATD for warmer weather and Cutter for cooler... while Prana for more casual cut.
