Does it really matter?
In my opinion it does. When I look at a portrait, I see a person posing. I will notice the wardrobe, body language and anything else I see in the picture. When done right, I'll receive the intended message it's trying to convey. It's branding. But when I look at a headshot, my eyes continue to shift back to their eyes, and that is a powerful way to connect. It's all about the individual, and I'm not distracted by clothing, signs, hands, etc. It's personal branding.
