We've had Movember, but now it's time for Decembrow – a fun way for feminists to grow a 'unibrow' to raise money for charity

What do Ava Gardner, Frida Kahlo, Jodie Foster, Keira Knightley and Brooke Shields have in common? You've got it – beautiful bushy eyebrows. And now you can too. A campaign led by Feministing, an online feminist community, has proposed growing a "unibrow" this month for a charitable cause of your choice.

Decembrow, inspired by the huge popularity of the unibrow in Tajikistan, is the female counterpart to Movember – a moustache-growing charity event held during November to raise money and awareness for men's health issues, including prostate cancer.

Unsurprisingly, there have already been disparaging comments from anti-feminist groups, such as the religious group Concerned Women for America, whose CEO thinks it is "curious that feminists would choose to embrace facial hair", before quipping: "How is that different than any other month of the year?" Well, considering how often the words "hairy" and "feminist" appear in the same sentence, we may as well live up to the stereotypes for a good cause.

Grand dames of 1930s Hollywood movies such as Marlene Dietrich may have gone for pencil brows, but many women know that the fuller look makes you look younger. So much so that a friend of mine once refused to do a live interview on TV until the runner fetched her an eyebrow pencil from the local pharmacy.

I approve of the natural look, and used to have power eyebrows until middle age hit and they began to thin. That's right, young readers, they start to recede once you hit 40. I may have to get the Brylcreem out and do a comb-over if this carries on. But in the meantime, rather than sleep with a moustached man in order to support the Movember campaign (I swear it was seriously suggested by some campaigners as a way women can support the cause), I will be popping down to my local fancy-dress store and buying a stick-on monobrow to show solidarity with my sisters.
