Joe Pinsker wrote about research that indicates that wearing formal attire changes how people interact with the world:

• Wearing formal clothes seems to make people feel powerful.
• While wearing them people think more holistically rather than about fine-grained details.
• Similarly wearing a Doctor’s white coat can make a person more attentive.
• However if the wearer believes that the same coat belongs to a painter the effect is no longer observed.

Read about how the study was conducted, and why the effect may get stronger in the years to come over here.
