Designed by women, for women. Our undies have got you covered!

Why AuntFlo?
Because 1 in 5 people who menstruate are having to use improvised period care because they cannot afford to it.
AuntFlo was born to help provide free and dignified access to period products to those who are struggling with period poverty.
AuntFlo was born with a passion to help girls. Since it was created, AuntFlo has connected with Share The Dignity, an Aussie organisation that identified a genuine need to provide vulnerable women in our community with essential sanitary products.

We are now proudly supporting Share The Dignity with our Pink Donation Undies, in which a portion of these profits go towards vulnerable women in Australia.
