My masculine guess to this predictable behaviour is the animal instinct in men that rings a bell whenever a female’s body is more visually defined.
Call me an odd ball, but women in uniform have always turned my head to take a second look. Not for sexual reasons but simply out of admiration and respect for what they do and the authority they represent. From transit operators, emergency and security staff, firefighters, police officers and military personnel, these remarkable women in uniform never cease to amaze me.
