Help me with ideas to upcycle my damaged jeans?

Hi all,

I recently went on a monsoon trip and due to not drying the pair of jeans properly, they caught mold.

I managed to get them cleaned and remove the mold, but the specific spots are now white patches.

Any ideas on how I could upcycle these, as the pair is still good, just cosmetically damaged and I don't feel like throwing it away.
