A long time ago, one of my favorite radio stations (Fresh 92.7) used to have T-Shirts for the Sims to wear in The Sims (the original).
So years gone by and sadly there wasn't any for The Sims 2 and/or 3, not to mention the file that Fresh hosted are no longer there.
With that said, I decided to make some of my own for The Sims 4.
Bear in mind that this is my first time of doing something like this, so the quality might be a little bit par.
It's only available in black and white & for Young Adults up to Elders.
Tools I've used : GIMP 2.8 (For cleaning up the logo), Paint.Net & Sims 4 Studio
Community radio station Fresh 92.7, dedicated to the youth of Adelaide.
