This study creates a mini collection of teen clothing with an ocean theme by combining creativity, sustainability, and digital innovation. Oceanic beauty is transformed into expressive, practical, and environmentally conscious fashion by drawing inspiration from marine elements like corals, shells, seaweed, and waves. The research uses digital textile printing, computer-aided design (CAD), and nature-inspired aesthetics in conjunction with the Double Diamond design framework (Discover, Define, Develop, Deliver) to increase production sustainability, decrease waste, and improve precision. Because of their comfort, breathability, and environmental advantages, eco-friendly materials like linen, bamboo, and organic cotton were selected. Seaweed biomaterials were not physically utilized, but their conceptual impact—drawn from Smelik's (2018) new materialism theory—highlights the interdependence of technology, nature, and humans. The final collection, which includes the Coral Dream Dress, Sea Breeze Set, and Marine Explorer Hoodie, exemplifies how digital innovation and sustainable design can produce meaningful, responsible, and fashionable teen fashion. It also reflects adaptability, individuality, and ecological awareness.
