I am creating a female character using an outfit from the G2 body composer kit 2. I need to have a long sleeve jacket which I can turn completely black. Initially the upper2_02 jacket looked ideal... but unfortunately it has a cleavage which is not appropriate for the animated character I need to create!

I then noticed that Upper_2 01 jacket didn't have a cleavage, but it has a neck scarf which I want to change for a normal neck. I can see that this neck scarf sprite replaces the normal default neck. All I want to do is remove the neck scarf and replace it with a default flesh coloured neck without having to create the actual artwork myself. I have managed to delete the neck scarf, but cannot work out how to replace it with the standard neck? I hope it is possible. 

It would be a life saver if someone could provide me with instructions on how to do it step by step as I am very new to this program.
