Development of Size-Adaptive Pilot Garments for Children Aged 12–24 Months Based on ASTM D4910 Size Data and Consumer Responses

This study investigated parental needs for size-adaptive garments for toddlers, aiming to address issues of fit and responsible consumption. The four-stage project involved a survey of 25 parents to determine parents’ needs and interest in size-adaptive garments, an analysis of ASTM D4910 size data and size charts of children's apparel, the development of three size-adaptive pilot garments, and evaluation of prototype garments with parents. The researchers revealed a preference among parents for size-adaptive garments, emphasizing vertical growth adjustments. Survey participants expressed interest in responsible consumption, highlighting longevity, and durability as key factors for success of a size-adaptive children's apparel. The proposed size-adaptive garments align with Gilmore and Pine II adaptive customizer approach, which emphasizes products that change functionality and representation to meet customer needs without altering the product itself. Findings suggest potential benefits for the children's apparel industry, such as reducing size offerings and accommodating diverse toddlers’ body proportions.
