here's one that's kinda similiar: https://www.amazon.com/PASLTER-Overcoat-Removable-Breasted-Business/dp/B08L98P69H/ref=sr_1_5?crid=KU9OKH7ZR8FM&keywords=blue+fur+trench+coat&qid=1660597127&sprefix=blue+fur+trench+coat%2Caps%2C116&sr=8-5

but if all else, find a blue trench coat and try to buy a bit of cream fleece or fur and sew it on, if you can. I'd suggest searching "Blue fur trench coat" as that'd probably give you the best results.
