All products shown after November 2015 that are from unsustainable and unethical retailers (Topshop, some brands at Target, Forever21...) were purchased before I was educated on the harms of fast fashion. But, as mentioned in a blog post, sustainability and ethical fashion isn't about your past, but rather your future. I have kept these purchases in order to reduce environmental harm that is caused from disposing of this clothing. With that being said, all of the products linked under the pieces or under "similar" are all from sustainable brands.
If there are any questions regarding this, please email me at: firstname.lastname@example.org and I will be more than happy to answer any questions. Brunette with a Budget is a 100% transparent company and website and any questions regarding sustainability and ethics will be answered.
