how to add an "inside shirt" with a created player

can anyone give me a tutorial on how to add an "inside shirt" with a created player? thanks

if you're wondering what an "inside shirt" means.. it looks similiar to this.

i just grabbed that pic from a topic here..

anyone?

its done by editing the player's CF and arm tattoo files.

jao how do u do that though? i know its with db commander but what numbers do u need to change it??

not so much DBF editing but more extracting fsh files and editing textures.
