If Kathryn Kemp-Griffin has her way, women around the world will be tossing their bras next month — not in protest, but as a gesture of solidarity in the battle against breast cancer.

The Pink Bra Toss, one of the liveliest annual events in the fight against breast cancer, returns for the eighth year on Sunday, May 14. And this time, Kemp-Griffin is hoping to turn it into a global event.

The Canadian-born author of Paris Undressed and host of the Paris Lingerie Tours also founded the charitable organization Pink Bra Bazaar to organize the annual outdoor bra toss at the Trocadéro, against the backdrop of the Eiffel Tower.

The goal of the colourful spring ritual — which attracts men, women and children, many in costume — is “to make the bra a symbol of lifelong breast health, reminding women daily to make the right decisions for themselves,” the organization says.

“By tossing our bras we help liberate the taboos surrounding breast cancer. This symbolic gesture filling the sky around the world unites women and men of all ages in celebration of breast health.”

This year, the organization is inviting women, groups and businesses around the world to hold their own local bra toss in an effort to spread Pink Bra Bazaar’s message about breast health education and support.

Participating groups are invited to register local events on the organization’s website to receive support in setting up their own bra toss. Registration is free and more details can be found here. They’ll even help you learn the event’s theme song, “I Love My Boobs”, which is a highlight of the yearly bra toss.

Pink Bra Bazaar, whose motto is “Push Up the Fight Against Breast Cancer”, also hosts a series of two-hour creative workshops in Paris in which women and girls decorate bras and share experiences and education about breast health.

That effort is supported by its Pink Bra Box campaign each October, in which women are encouraged to donate used bras at participating retailers to be used in the group’s educational ateliers.
