Undyed Organic Low Rise Panties – Sustain by Kat

Undyed Organic Low Rise Panties – Sustain by Kat

We created underwear having a modern silhouette without the dependence on synthetic fabrics or trims. Made with 100% organic cotton fabric and trim and natural rubber elastic, our underwear is available in undyed white, undyed colorgrown organic cotton and organic plant dyes.

While many companies are now using organic cotton for undergarments, most still heavily rely on petroleum products for synthetic dyes, thread and elastic. We hate itchy seams and things bad for the environment, so we set out to make the first 100% natural underwear.

After a year of researching and designing, we created underwear having a modern silhouette without the dependence on synthetic fabrics or trims. Made with 100% organic cotton fabric and trim and natural rubber elastic, our underwear is available in undyed white, and undyed colorgrown organic cotton (yes, cotton grows in color!). 

Ethically designed and manufactured in Los Angeles.

Made with:

  • 100% GOTS certified organic cotton (undyed)
  • 100% organic hemp lining at the curve
  • Natural rubber elastic covered in undyed GOTS certified organic cotton
  • 100% GOTS certified organic cotton sewing thread at the seams (undyed)

For sanitary reasons, we cannot except returns on panties.
