Which technological advancement did Akira utilize for a wedding dress in 2003?

The correct answer highlights Akira's innovative use of laser-cut calico for a wedding dress in 2003. This technique involves using lasers to cut intricate designs into fabric, allowing for precise patterns that can enhance the aesthetic appeal of garments. The laser technology enables designers to create detailed and delicate shapes that would be difficult to achieve through traditional cutting methods, showcasing a blend of craftsmanship and modern technology. Akira's application of this technology in a wedding dress not only demonstrates creativity but also a commitment to integrating advanced methods into textile design, resulting in visually striking and unique pieces.

Other choices, while relevant to discussions of contemporary fashion and textile processes, do not accurately represent Akira's work in this particular instance. 3D printing, wearable technology, and eco-dyeing technology are notable advancements in their own right, each contributing to the evolution of fashion design and sustainability, but they are not what Akira was recognized for in the context of the wedding dress created in 2003.
