How to replace a refugee skin?

Hey all you facepunchers! I have figured out how to make skins to Gmod just yesterday, but what I could not figure out is how you replace the refugee models skin with the custom made one?

I just can’t seem to find the right file…

oh and the question involves both male and female refugee skins

and for those who don’t know the refugees are the ones with the white shirt (default)

I would like to have a answer!

Urgh… fuck it nevermind thanks for nothing I guess

your… welcome?
