Yes, and that is because it makes you disappear. You read it right : wearing black actually makes you disappear. Think about it.
If you’re at a networking meeting sitting at a table full of well-dressed women, the women wearing color and pattern are the ones who come across as the most approachable and confident. They are the ones you notice. The women wearing black? They disappear. You don’t even see them.
Now black dress pants/jeans as a part of most wardrobes are useful. They can be flattering and versatile, however I don’t approve of the play safe mostly-black wardrobes.
Wearing black is often seen as professional. But it actually diminishes you. It makes you shrink. Wear black if you want to blend into the background.
