The diploma project focuses on the interior design of a children's clothing store offering garments made from milk fiber, developed for the brand Je M’aime by Duedilatte. This Italo-Swiss brand specializes in innovative products crafted from natural casein, a unique and unexpected material that serves as the central inspiration for the entire spatial concept. The design transcends the conventional boundaries of commercial interiors, creating a functional, aesthetically refined, and meaning-rich environment that conveys the brand’s narrative and values. The interior embodies the principles of slow fashion—sustainability, quality, and respect for natural resources—serving as a platform for dialogue between the brand and the conscious consumer. The visual language of the space draws on the essence of milk—its softness, purity, and fluidity—which is reflected in the choice of materials, colors, and organic forms throughout the furnishings. The space offers a multisensory and emotionally engaging experience, while fully accommodating the operational needs of a retail environment. The project is set within Apollo Business Center 2 in Bratislava—a vibrant urban context ideally suited for reaching the modern, eco-aware clientele. The result is an interior concept that harmoniously integrates design, narrative, and brand philosophy, demonstrating that even a retail environment can become a catalyst for positive change.
