Repro tunic color fading

[Venturefan260]

Hello.

I have this old repro tunic but the field-gray color seems to have faded to a yellowy shade due to sunlight exposure perhaps? Is there any way to restore the color, or should I just fade the rest of the tunic so it would be single colored?

Thats why I have the window in my room boarded up!

I keep my tunics in the dark too, but this one was like this when I bought it.
