Hmmm. I prefer a button-down for more casual situations. In fact, unless I am wearing a four-in-hand tie, I only wear button-downs. and for fairly casual situations with a tie, I still wear button-donws. But . . .

if I am in a dressier situation requiring a tie and nicer jacket, I wear either a spread or standard point collar. Unless. . .

it is more of a black tie or formal sitation. In which case I would wear a bow tie--self-tied and never pre-tied--probably with a wing-collared shirt, complete with pleated front.

So, I guess the answer to your questin is, yep. I wear 'em all.
