    Love the options, there’s just one thing I’m a bit confused about. With regards to the last option, Isn’t bamboo viscose a type of rayon? Aren’t the chemicals used linked to health and environmental issues? Or am I just way off?

      Bamboo is complicated because not all bamboo fabric is made the same way. Yes it’s a type of rayon and can be very damaging, however some brands are producing their bamboo fabric much more sustainably than others. Some key things to look for are bamboo that is sustainably farmed, manufactured in a ‘closed loop’ system which means the chemicals and waste water is being captured and reused instead of dumped, and also Oeko-Tex certified bamboo which looks for toxic chemicals (you can read more about oeko-tex here: https://mygreencloset.com/what-is-oeko-tex/). It’s not a material we typically recommend but there are some brands who seem to be much more responsible with their bamboo sourcing/manufacturing.

    Hi there,

    My fiancee and I are trying to live as sustainably as possible and have since dreaded looking to replace our worn out clothes trying to find new sustainable and ethically sourced clothing. I have looked all through your many suggestions but failed to find strictly g-string underwear, which is her must. Would you be able to help our search?

    Thank you so much!
