The Reality of Fast Fashion.
WAYS YOU CAN HELP
Buy less "trendy" fashion items and thrift more.
If you live in an area where you do not have access to a thrift store, places like Etsy or Depop online.
Buy from ethical. Support small business. If this option is still limited to your style try doing research on brands that are at least striving to create better working conditions for their manufacturers.
Check quality of clothing, the right piece can last you months-years depending on how well you take care of it.
Resell or donate. When you are done with your pieces donate to those in need or try reselling if you need the extra cash back.
