Not Just Another Fashion Label


Cousin Billie is an Australian women’s Fashion Label combining simple modesty with feminine and flattering styles.

Founded in 2018 by designer Petula Savin, Cousin Billie is the only modest label whose garments are all ethically manufactured in Australia.

Having spoken to hundreds of women over the years, it was evident that so many shared the same struggle - to find a reliable source for tasteful, well-made clothes.

In a world of fast-paced trends, revealing cuts and ‘sack-like’ silhouettes, finding flattering and timeless fashion was near impossible.

With an emphasis on quality fabrics and unique prints and colours, Cousin Billie provides fresh collections which are tailored to embrace and conceal each curve of your silhouette for ultimate femininity. Guaranteed to never make you feel conscious of what you’re wearing, these stylish garments are bringing class and decorum back to the fashion industry.

Each limited-edition design is created with a desire for you to feel quiet confidence in yourself, to prove that good manners still exist, and to earn respect through your values and the way you dress.

Available exclusively online with a very accommodating returns/exchange policy, you can look through the latest collections of styles here.

Whether it’s to land a job interview, make a good impression on a first date or simply wow your workplace or classroom, Cousin Billie have you covered. Quite literally.


About the Founder 


Cousin Billie Modest Fashion Australian Founder Head Designer

Petula was raised on a dairy farm in South-East Queensland where her Grandparents raised their 10 children.

Surrounded by a large and loving family, Petula has been influenced by the values and standards of good-living, genuine people, which have helped to shape the vision for this brand.

‘I was concerned by what was being accepted as ‘appropriate clothing’. Especially by the younger girls.’

‘It’s a struggle for women who have self-respect to find fashion that complements their integrity. The fashion of today seems to scream ‘cheap and nasty’. I wanted to provide something different. Something tasteful – both physically and morally.’

‘My desire is that women see qualities in these garments that meaningfully represent their own personal style and values.’

Petula lives with her husband and busy little 3yo and 1yo in Hamilton, Victoria where her husband works in the Livestock Industry. They also run a few beef cattle on the side. They are expecting their third child in 2024.




If you’ve never felt 100% flattered by an outfit, it’s not your fault. Turns out - flattering fashion is hard to find.
