It isn't outlandish to suspect in context, no. But it also just raises a load of questions, especially when they seem to also have a social media manager who makes these sort of claims (a job which really is just being a hawker), and there is no real information around from independent mouths who aren't invested in selling something.
Why have people claimed it "looks like matchless" when it's designed by Renee April, looks like and incorporates design cues shared by all the other gear she designed for the movie (Luv, extras) and using magnets and shoulder caps is fairly widespread practise?
Why do we see so many garments being manufactured in-house in the behind the scenes footage?
Why did Renee April mention that she and her staff ran out of the material and so only made 15 instead of 20 jackets, if it was outsourced to a large manufacturer?
Why do the claims come from a single unverified source who "can't name their source" but goes on in the same post to identify them as "a guy who doubles for Gosling"?
Why did this source name Bulgaria when the filming took place in Hungary, and didn't seem to know much else?
Where is the parka that Ford was supposedly wearing also by Matchless (claim in the same post), which has never been seen?
Seems like a guy who likes Matchless got excited and blurted out some sketchy information. I'd love for there to be more information about the thing available, but there doesn't seem to be at all, and everything I found ranged from big questionmarks, to spurious.
Again, I'm not here to ****can people, while I'm sure someone will take this kind of stuff personally, fair enough. I just want for information to be verifiable or at least have some kind of basis beyond "man I bought a dog from down the pub", "internet", "they say", etc.
