These are the 3 themed packs I did for Fallout 4's "Graphic T-Shirt Pack" from Creation Club. There's the Comic Pack, Vault-Tec, and Brands Pack.
I used 3DS Max for base outfit design and ZBrush for sculpting. Quixel Suite w/ Photoshop CC 2017 for my textures, and Bethesda's Creation Kit for implementation.
I would have loved to have done more (especially with the Brands pack, I wanted to explore more in-game brands) but for time sake, these are the ones that stuck out the most.
If you're interested in having this in your game, you can purchase it from the Creation Club!
