    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!
