Ex-Canadian Prime Minister Kim Campbell says women on television shouldn't bare their arms as it's "demeaning" and can "undermine credibility and gravitas".
Ms Campbell, the 19th Prime Minister of Canada, tweeted that she's amazed how many women on television wear sleeveless dresses and "often when sitting with suited men".
"I have always felt it was demeaning to the women and this suggests that I am right. Bare arms undermine credibility and gravitas!"
She shared a link to Yale research on the perceptions of people - both men and women - who bare their skin.
The study, Sexiness and Sweaters: The Psychology of Objectification, found that people who wear less clothing are perceived to be less competent and have less self-control.
People who wore less clothing were also perceived to be more sensitive, emotional and more in need of protection.
This perception meant they were less likely to be perceived as powerful.
The study found the perceptions were the same for men and women.
