Graphic T-Shirt Designs Needed

I’m launching a fresh casual-wear label and the very first collection is all about standout graphic T-shirts. The brief is simple: create original artwork that captures an easygoing, modern vibe yet feels distinctive enough to spark conversation when someone wears it.

Here’s what I need from you:
• 5–7 unique graphic T-shirt concepts, each delivered as layered, print-ready files (AI or PSD) plus high-resolution PNG mock-ups.
• A short design rationale for every piece so I understand the story and can use it later in marketing copy.
• Basic tech-pack details—colour specs, dimensions, and recommended fabric weight—so my manufacturer can move straight into sampling.

Acceptance criteria
• Artwork must be 100% original and vector-based for easy scaling.
• Colours sit within CMYK gamut and use no more than six spot colours per design.
• Files pass a quick print test on a 12"×16" template without visible pixelation or artefacts.

If you live and breathe Adobe Illustrator or have a favourite Procreate-to-vector workflow, even better—just let me know. Once these first graphics are dialled in, there’s plenty more room to expand into hoodies, caps, and packaging, so think of this as the start of an ongoing partnership.
