Dressing like subordinates lowers perceived leadership capability.

Evidence

Non-verbal forms of vertical communication express themselves not only in momentary behaviors, but also, for example, in things like office furnishings or clothing. For example, soccer coaches who wear similar training clothes to their players at games or press conferences are regularly seen by the public as more affable but less capable of leadership than those who show up to such appointments in suits. — Holm Gero Hümmler, Ulrike Schiesser, Fact and Prejudice, 584
