Rachel Mackley had appeared on the BBC News channel's early-morning bulletin in a skin-tight top with her assets clearly outlined, but when she appeared at 8am she was wearing a modest pinstriped jacket.
It is not clear if it was bosses who had ordered Mackley to slip into something less revealing, or if it was just a bit cold in the Beeb's central London studios.
On web forum Digital Spy, Mackley's are listed among the Best Boobs on TV, and there are several clips of her weather reports on YouTube that show her ample bosom.
Sun reader John Murphy, who was watching BBC News, feared Mackley had been "censored" by joyless corporation execs.
"I had an image in my head of some BBC boss waking up, seeing this and phoning the London studio to say, 'Put those boobies away'," the Sun quoted him as saying.
"If so, it shows the BBC certainly isn't 'dumbing down'. But Rachel has nothing to be ashamed of," he stated. (ANI)
