Our Story

Sophie and Marie, the two entrepreneurs who wanted to create the world’s most sustainable tights


Who are we?


We are two young French women, Sophie and Marie, who met in the workplace in London. Together, we decided to embark with passion on a new adventure.

Ambition doesn’t come unprepared, though! Before creating Billi London, we trained and worked in marketing, new business, fashion, and eco-responsibility. Our collaboration is based on complementarity.


How did we meet?


Through work. At the time, we were working for large companies, and didn’t know we shared the same dream of fixing the hosiery industry! Though we could perhaps have guessed it, given how often we both wore tights

Where does our brand name come from?


“Billi” is my nickname (Sophie). All my friends call me Billi. It’s my last name - the first part of my last name, actually. Its multilingual aspect reflects our own journey: the name “Billi” exists in French and English, but also in Italian (I have Italian origins, and our tights are manufactured in Italy). “Billi” was also very meaningful for Marie, because that’s her own sister’s nickname! So we both had a story with “Billi”… 


We added “London”, as a tribute to the city where we first met. London is an incredibly exciting place for any fashion-lover!

Why tights?


Firstly, because we are tights’ biggest fans! We love how they effortlessly and instantly elevate any outfit. Sadly, the environmental impact of tights is real (several tons of waste each year, taking between 40 to 100 years to degrade), but often overlooked.


Secondly, because we felt that shopping for tights – a sensual product if there ever was one – should be a much more enjoyable experience! Where was the glamour, playfulness, and elegance?


We wanted to create the world’s most sustainable tights, which would also be resistant, comfortable, soft, and sexy. We’ve been obsessed with this idea ever since. Although we now have a whole legwear collection including socks and leggings, it all started with tights.

What do we want?


To reduce waste in the textile industry and encourage the transition towards a circular economy. That’s why we wanted to go to the very root of the problem – yes, tights made of recycled materials existed, but these would still take up to 100 years to degrade in landfill… There had to be another solution.


How are we doing it?


With high tech tools. We use Amni Soul Eco®, the first polyamide yarn produced in a more sustainable way and that biodegrades in around 5 years after disposal in a sanitary landfill. Yes, 20 times faster than traditional tights! 

While such fibres existed when we first started in 2019, they had never – and we really mean never – been applied to tights. We were the very first in the world to work on this… Now you understand why it took 2 years of research and development!

Everything happens for a reason
