**T-Shirt Design Concept: “Cosmic Wave”**

**Front:**
A bold, dynamic graphic of a stylized wave that flows across the chest. This wave is no ordinary wave—it’s an intricate fusion of vibrant cosmic elements, featuring nebula clouds, star clusters, and swirling galaxies within the crest. The wave’s form resembles the natural curves of a tidal wave but with a cosmic twist, as if the wave itself is made from stardust and planetary rings.

The wave begins in a deep shade of midnight blue at the left side of the chest, gradually transitioning through purples, magentas, and electric blues, and finishing with fiery oranges and reds at the right side. This gradient effect creates a sense of movement, as if the wave is crashing toward the viewer. Along the crest of the wave, small scattered stars and planets add depth and wonder.

**Back:**
At the top center of the back, there’s a minimalist, small symbol—a crescent moon intertwined with a swirl of stars, representing the connection between the earthly and the cosmic. Beneath this symbol, there’s a delicate text in a futuristic font: *”Ride the cosmic current.”* The text is subtle yet impactful, positioned just above the waist.

**Style Elements:**
– The t-shirt itself is a deep, dark navy or black to enhance the vibrancy of the cosmic colors and create contrast with the glowing effect of the wave.
– The fabric has a slightly iridescent sheen, mimicking the light-reflective quality of stars and planets, adding an extra layer of depth to the design.
– The print uses a mix of screen printing and glow-in-the-dark ink for the stars and cosmic elements, so parts of the design glow faintly in the dark, enhancing the theme of celestial exploration.

**Overall Feel:**
The design evokes a sense of adventure and wonder, as if the wearer is embarking on a journey through the cosmos, riding the waves of the universe itself. It’s perfect for those who are fascinated by space, science fiction, or simply appreciate unique, imaginative art.
