"pilot livery" in first person

[SPAS79]

I did a cursory search here and on google but could not find anything related to this. 

I have liveries that show different pilot garments (e.g. all green, blue, camo other than multicam etc) but some of them, when in first person, keep showing multicam on the pilot's body (i.e. not showing the olive drab overalls). They work fine in external (F2-3-4...) view. 

Any idea why this is happening?

Check cockpit textures, not only external.
