I've got at least 10, half of which are OCBD for work. After that, I've got a two spread collars, one RL casual, one Land's End casual with a herringbone pattern that a favorite of mine. I'm hoping to replace my all white button downs today. Most were bought when I was running marathons as a hobby, and now that I run less my shoulders and chest are broadening from weight training and the sleeves are too short. I've never been much for color in my business wear, but I may get a couple in the mix this time around...
