The reasons to wear a black shirt are far simpler than the author purports: contrast & focus.

I learned this while presenting. If you wear clothing with a slogan, you are giving your audience a potential distraction, or something to read while they should be listening. Even a colored shirt can be a potential distraction, unless it is worn specifically for the purpose of brand association.

This is why you should not wear a clever slogan while presenting, even if it's your own brand.

As a light, Caucasian presenter, I prefer to wear a dark, featureless shirt because it highlights my facial features and directs the audience to my face and speech. Except for my hands, which I can use for pointing or demonstrating a process, in which case, I don't want a long sleeved-shirt to get in the way, and when there are plenty of lights, to stay cool.

Interesting. I prefer white or charcoal grey pocket Ts as daily wear. I've had some black Ts, but as a person of pallor I found the contrast a bit stark.

I think I look best in the white shirts, but for a presentation I can see the value of going with a dark one.

Even simpler, black is slimming.
