I have this concha belt that I have had for years. I still love it but it doesn't fit anymore. I had tried having belts lenthened at the shoe repair store at minimal success and too much expense. For this belt I decided to cut off the buckles and glue (using shoe-goo) the original belt to another larger belt.
Voila! Worked like a hot darn.
