Well, sure. If you're at the extreme of the spectrum in terms of a physical attribute, choosing clothing at the opposite extreme probably isn't the best idea. But for more average guy, I grow suspicious once notch lapels start inching past the midpoint of the chest. Slightly narrow > slightly too wide. Minimalism over excess. But either extreme is no good. In the post you link, the problem with the skinny lapel isn't just that it's too skinny but also that it's too stubby.
