so, i went to LV yesterday and they said YES the pochette leather can be changed for about £30 and the ellipse would be about £300. Sounds like alot but i will get it done as a new ellipse is £700 and i love that bag soooooo much. I gave the pochette in, i already have a new strap with pale vachetta so they will change the zip for me with the leather bit attached to it, and VOILA a brand new pochette!! btw they pochette i bought 12 years ago for £90 and now it costs £205 so spending £30 on the repair and also £40 for new strap is much better than buying new accessory pochette!
i will post pics when i get it bak
