Unfortunately, chances are your closet has more than a few unsustainable garments of clothing. With the prevalence of the fast fashion industry nowadays, along with our society’s propensity for overconsumption, many of us have partaken in some form of unsustainability regarding our clothing.

However, that doesn’t mean it’s too late to commit to sustainability, and what better place to start than with sustainable underwear brands?!

Fast fashion not only impacts the overproduction of clothes, it also impacts the quality of said clothing. There are often dangerous chemicals involved in the making of unsustainable products, therefore harming both the producer and user of them.

Nowhere is this more concerning than with underwear. By nature, underwear is likely the most sensitive clothing item for most of us to buy. It is important for it to be comfortable and safe, however unsustainably renders these goals impossible.

Because of this, we have selected three of the best sustainable underwear brands we believe are an essential for every woman’s wardrobe. These brands provide you with safety, comfortability, and style all in a sustainable package. Wearing these, you can rest assured that you’ll be treating your body and the planet with the kindness they deserve.

Let’s Talk Fast Fashion

First and foremost we must talk about fast fashion, including:

  • Why it started
  • Its impact on the environment
  • How it promotes unethical labor
  • And its impact on human health

Why Did Fast Fashion Become a Mainstream Thing?

The rise of the industrial revolution in the early 1900s partially gave way to the rise of the fast fashion industry. The machines and practices developed during this time period made it simpler for clothes to be made, therefore allowing these clothes to sell for less money.

Present-day, this business model has been exploited to the max, with fast fashion brands churning out billions of items every single year. With the rise of trends, the rapid pace in which these trends change, and the rise of social media/influencer culture, the problem has only continued to worsen.

Additionally, these fast-fashion brands target those most likely to be swayed by low-prices and trendy styles, such as high school and college students.

What Type of Impact Does Fast Fashion Have on the Environment?

With the billions of items produced every year in fast fashion, only one percent of that is recycled towards new clothing. Therefore, the rest of that clothing is predominantly getting discarded in landfills.

Because of this overconsumption and lack of recyclization, fast fashion makes up 10 percent of our global CO2 emissions.

Another concerning fact is the fast fashion’s industry’s large contribution towards global wastewater and microplastics, both of which severely harms our waterways.

How Does Fast Fashion Promote Unethical Labor?

Similar to its negative impact on the environment, the fast fashion industry is absolutely devastating towards the effort for ethical labor.

Because of the inexpensive price the industry sells its clothes at, workers are often not paid a fair wage. In fact, studies show that fewer than two percent of all fast fashion factory employees make a livable wage.

Additionally, fast fashion is a huge contributor to child labor, evidenced this past summer by the popular brand Shein. Tik Tok users posted videos in which they showed their Shein packages and garments. On these items, workers wrote out pleas for help. Much of the handwriting and messages appeared to come from children working in their factories.

How Does Fast Fashion Harm Human Health?

Studies show that incredibly dangerous chemicals, such as PFAS and lead, have been found in fast fashion garments.

This is harmful for both the producer and wearer of these clothes, as exposure to these toxic chemicals are linked to health problems like skin, respiratory, and internal organ conditions.

Furthermore, especially for children, lead poisoning can be incredibly detrimental to developmental processes and health.

In order to show their commitment towards the environment even further, they also offer a tree planting program in which their customers can register for. This works by using a monthly fee to plant a certain number of trees in order to balance out customer CO2 use.

Their underwear features more basic pieces in gray, black, and rose-goldish hues, all great options for those looking to keep it simple.
