Minimalist Monochrome T-Shirt Design

I need a fresh, minimalist graphic for a T-shirt that will print cleanly in a single monochrome tone. The concept should rely on thoughtful negative space and simple line work rather than heavy textures or shading, so it stays crisp on both light and dark fabric.

Please deliver:
• A print-ready PNG (300 dpi, transparent background).
• The original editable vector file (AI, SVG, or EPS) so I can scale or tweak it later if needed.

I usually work with Adobe Illustrator mock-ups, so keeping everything in vector paths will help me run quick test prints. Let me know if you need garment templates or any extra brand details before starting.
