I finally went in game to play, I was customizing a male sim I downloaded off the gallery. I saw these shirts and wanted him to wear them.  However they had this colour block across the front which really bothered me. So I exited the game and promptly recoloured so I could use them.

This creation is Non-default.
Mesh by EA.
Comes in 28 colours.
Custom Thumbnail included.
