When a white shirt collar and cuffs come to mind, they most often accompany a blue shirt body. That's not, however, the best use of a white collar.
In the photo, musician Charlie Watts wears white collar and cuffs with an aggressively striped shirt body. The plain collar is the reason the shirt pattern works in this context, as it often is with dark and strongly patterned shirts. With a self collar, that shirt would mate with solid suitings and not much else.
The next time you're considering a large tape stripe, a large check or an unusually dark shirt fabric, have it made with a white collar and cuffs. The shirt will be wearable in many more combinations than the same shirt with a self collar.
