You will need to have the Glamor Life stuff pack installed in order to use these in your game.
Here are 8 re-colours of the casual outfit for adult guys that came in the Glamor Life stuff pack.
They are organised into 2 sets with 4 outfits in each set.
Set 1.
Set 2.
If you want to use these as a base for doing your own re-colours, I would request that you ask permission as it took over 7 hours work to remove the stripes from the orignal textures in order to do these.
