The nation's most famous suit has sold on eBay, fetching a handsome $6500 for White Ribbon, the charity that campaigns to end violence against women.

Karl Stefanovic, co-presenter of the Nine Network's Today program, wore the blue suit for 12 months, making a not-so-subtle point about the unfair scrutiny to which his female colleagues are subjected.

Only after a year in which no one noticed or commented did Stefanovic reveal his cheeky experiment and then announced he would auction the well-worn suit, with proceeds to go to White Ribbon.

The cheap Burberry "knock-off" was optimistically listed on eBay as "super comfy, super stylish, super cool".
