After 6 months in fashion industry, I learned how to pay less and take better care for the earth

Data Science plus Fashion taught me how simple it is to buy sustainably

Why is sustainable clothing worth looking at?

Fashion industry contributes to global warming. The fashion industry is responsible for 10% of annual carbon emissions, more than all international flights and maritime shipping combined. According to world bank, at this pace, the fashion industry’s greenhouse gas emissions will surge more than 50 % by 2030.

Second-hand clothing cannot solve the issue. Yes, second-hand resale store like Vestiaire contributes to a more environmentally friendly fashion industry. However, looking at your own closet, how many of your clothes are from charity or second-hand store? For me, less than 10%, not to talk about how highly sensitive about hygiene of second-hand items after this pandemic.

Covid-19 made the call. After this tragedy, we better think twice how we can treasure what we have in a better way.

What is Sustainable Fashion?

To put it simple,

No one should die making a T-shirt

, and we shouldn’t be pouring toxins into our planet


Sustainable fashion is a process that creates ecological benefits and fosters social justice.

3 simple actions I learned

Some brands aim at providing good quality, sustainable items.

Here is a list of sustainable brands, which is based on composition analysis on over 1000 brands and 100,000 items. (The percentage means that among all the SKU of a certain brand, the proportion of sustainable versus non-sustainable materials. )

Check out these brands or click one of their random items on Farfetch. It is guaranteed they are the top sustainability leaders. Venroy and Reformation are highly environmental conscious and in affordable price range.

Everyone has a few favorite brands. Choose one that makes you proud.

I rarely looked at the composition tag when I bought clothes. But after gaining a basic knowledge from fashion industry, I found it is important and pretty easy to understand.

Below you can find the most commonly used sustainable materials from 100,000 clothes. Remember this, 80% of the time you can make the right choice.

Sustainable: Viscose, Linen, Organic Cotton

Non-sustainable: Polyester, Nylon, Triacetate

Taking a 5 second peek on the tag. You save the earth by choosing an item that is originated from the nature, biodegradable and manufactured with much less water.

3. Buy less, buy better

Save some purchases.

Choose a good brand.

Buy to care for the environment.
