In the early days of broadcasting, BTV (before television), the BBC newsreaders were made to dress formally: i.e. dinner suits for men and evening gowns for women newscasters.
Not that anybody, other than BBC staff, could actually see them reading the news. It was just the stuffy old rules that were applied by the BBC management then.
Now the pendulum has swung in the opposite direction. Smart casual, to coin a phrase, has been approved in many areas of broadcasting. Presenters can wear old jeans and trainers, no neckties required and various other dress modes are OK today.
Some presenters just look scruffy; I can't say I am in favour of some of these 'informal' styles but it does not bother me too much. I don't watch too much tv anyway.
However, what's this to do with 'Bare Bosom' I hear you scream. Tell us, show us, come clean!
