Very few pieces can look as crisp and put together as a button down shirt. When you find one that fits your body perfectly, you'll know--it will button easily, leave no gaps, and skim your torso. It might be tempting, when you find the perfect shirt, to live in that one piece forever, but that would be boring. Luckily there are endless variations on the classic standby, for every occasion.
My picks (concentrating on three-quarter length and long sleeve shirts today):
My perfect fit? The J. Crew three-quarter sleeve stretch shirt. You can see them here, here, and here (which doesn't span my entire collection).
What's your perfect fit? What types of details do you find most appealing to spice up a button-down?
