Artistic References

Iris van Herpen’s sculptural dresses, particularly from her Magnetic Motion collection , stand out due to their innovative use of magnetically-formed structures. In collaboration with artist and architect Philip Beesley, van Herpen explored the idea of energy fields and the invisible forces of magnetism as inspiration for her designs. To achieve the unique, sculptural look, she utilized magnetic fields to manipulate ferromagnetic liquids, creating intricate shapes that were then translated into wearable garments. The process involves applying magnets to a liquid solution containing magnetic particles, which allows the material to form into natural, organic patterns. These magnetically influenced formations were later 3D-printed into solid structures, resulting in garments that resemble natural crystal growths or alien-like textures. This method blends technology and nature, reflecting van Herpen’s philosophy of combining science with art in fashion design.
The collection, which also incorporated 3D printing and laser-cutting, features garments with highly detailed, sculptural shapes that seem to flow like frozen energy fields. Her designs push the boundaries of fashion by exploring how materials can be shaped beyond traditional methods, showing her pioneering vision in haute couture.
