For your minimalist t-shirt design, I propose an abstract composition featuring flowing, organic shapes that evoke a sense of modern art. Using pastel tones such as soft blues, pinks, and earthy neutrals, the design will be centered on the back of the shirt, creating a serene, balanced aesthetic. The shapes will be subtle and fluid, inspired by nature, ensuring the design feels both contemporary and timeless. The use of muted colors will keep the overall look minimalist and sophisticated. This unique design will add a touch of creative elegance while remaining versatile and easy to wear.
