Is there a rule of thumb for how the size of lapels a person can wear depends on their shoulder line? I guess it seems to me that smaller shoulder lines will wear wider lapels better and vice versa.

The reason I ask this is because the question came up when I was trying my NAS vest:

I love the vest and it's a keeper but for future reference it would be useful to know the answer. Right now I have to wear it open and I'm wondering if the "lapels" as shown in the picture sitting below my broader shoulders make the style fall short of killer on me. Of course, it could also be that no matter what I just feel wide right now anyway.

Thanks!

Thanks.
