Hi, you can buy the large Noe LV strap from Louis Vuitton, I believe it sells for $250.00. Yes it is expensive but will last forever. I had my first Noe bag for over 18 years before I gave it to my friend and she still wears it. Of course I clean my leather straps so it was never dirty looking. My friend gave me a new Noe strap that she bought probably 18-20 years ago and it was tucked away in a bag. She never even used it. So I was very happy to get it. I like to feel my shoulder bags are sturdy and with the Noe strap they are. I feel very secure grabbing my bags on and off my shoulders and did not feel like this with the reg. BBag straps. The regular courier strap was hard to stay on my shoulder and just felt strange. Same with the twiggy and city straps, I didn't like them. I am sure other leather straps would work well but I personally love the large Noe strap because it has the two ends that have the holes for the strap to be hooked on each side, like you do with a belt. I personally don't like the clip straps that you just clasp on a bag, I always think they are a bit cheap looking (just my personal opinion).
