I love Savane's.  They fit so well.  These have a subtle herringbone pattern that enables you to wear them with virtually any shirt.  I've dressed up with them with a tie and jacket and dressed down with a casual shirt.

They also stay very well pressed throughout the day.
They're a little thin, so don't plan on wearing them on a cold Minnesota type day.  But for this Jersey guy, they'll work 10 out of 12 months.
