If you are in the UK I would recommend checking out www.theseam.uk , I am sure you can have it repaired.
I am sure this too can be fixed if you find the right person, I linked to a network of crafters earlier in this thread, you will find one there! Invisible mending is an artform. Google it and you will be surprised🥰OP, I feel your pain! This happened to me but to my camel colored long coat. I was devastated and had only worn it once when I noticed the damage. I was so grossed out that I got my coat dry cleaned and asked the owner if she could fix it. She said it couldn’t be fixed. I kept the coat and wonder what I should do with it also. The damage is on the shoulder and underneath the wrist. It’s not super obvious, but it’s def there. The part that really makes me sad is that I got it on my trip to London and it wasn’t cheap.
