Sézane is a French based fashion brand pioneered by Morgane Sézalory. The brand itself has been in the works since 2013, but it engages with many ideas that are new and innovative to the fashion industry. They implement and advocate sustainable and environmentally friendly fashion practices. The brand emphasizes its transparency and their contribution to humanitarian and environmental causes.

Their growing customer base and popularity on an international scale can be attributed to their trendy designs and their fashion forward French aesthetic. The Parisian look they advertise is particularly attractive given the long history of French fashion, coupled with their activities in philanthropist affairs.



The transparency they advertise isn’t all talk, they make a lot of their data available for anyone to access. On their website you can see a list of the countries they work with, as well as the extent of their involvement, for example China produces all of their silk products. You can also look up the materials they use, the sources they come from, and how they are made.

Philanthropic work

They operate a philanthropic program, Demain, which focuses on providing support to underprivileged children. All of the information regarding the funds that go into, and come out of, Demain are available on their website, so it does appear to be a dependable program.

They not only advocate for fair and humane working conditions, but they try to implement them in their own factories. A good portion of their clothes are manufactured in China, a well-known hub of poor factory conditions and inhumane working conditions. But they regularly have inspections done by third party organizations as well as their own staff.

10% of their fabrics are environmentally friendly, and they are planning on expanding their usage in the coming years, as well as reducing their usage of harmful fabrics, which currently sits at 15%.

Organic dyes

They use vegetable dyes and other non-toxic chemicals during manufacturing in two thirds of their leather products. But they are implementing more non-toxic dyes throughout their manufacturing.


As mentioned, their environmental initiatives, while better than conventional fashion practices, are lacking. They’re currently in a transitional phase from conventional fabrics to environmentally friendly fabrics, so they have a long way to go before they can claim substantially conservational practices. Overall their materials can be improved.

Their recycling initiatives are also lacking. They do sell clothes from photoshoots and promotional content, but they don’t seem to have initiatives set up in house for scrap fabrics, office utilities, and other areas of their business.


Sézane’s biggest merit seems to come from Demain, a great program that is both transparent and effective in its goal of supporting underprivileged children. While they have taken initiatives regarding the humanitarian impact of their practices, they aren’t as environmentally friendly as we would hope. This does seem to be changing with time, and as they pass this transitional period, we should be seeing a rise in sustainable practices.
