Strap elastic does all the heavy lifting in a bra, and as such, in both our bras as well as conventional bras, they are the first to go. Often the bra itself has a few more years left in it after the straps have given up the ghost, and so for those who'd like to repair, we can offer extra strapping to allow you to do that. We will send you 90cm of 13mm (or new 20mm black or ECRU) strap elastic in your chosen colour, plenty for 2 straps. We are currently carrying minimal stock of straps as we transition to new elastics, however you can purchase our original organic cotton/rubber direct from our supplier In Germany. You can also replace with conventional elastic to lengthen the lifespan of your bra, just bin rather than worm it at end of life. **NB - Please ensure you are buying the correct width of elastic to match the metal on your bra, if you have 13mm wide straps currently, the 20mm will not fit the rings and sliders** You need to either hand or machine sew around the rings already on the bra, and put the sliders back on. We'd love to extend the life of your bras. Please let us know your feedback when you've repaired!
