Ready to wear garment collection preparation consists of several processes from design idea to selling to last consumer. There are various factors that effect the product design and product cost. If the designed products are for babies and kids groups, suppliers need to care about health and safety conditions besides the design, aesthetics, quality, cost and marketability. At this research, principles and steps of 0-12 age garment collection processes were examined; factors that effect the product cost and product design processes were elaborated. Because of its big marketspace at Turkish textile export, Europe was determined as target market at this study. "Traditional costing" and "target costing" methods from contemporary costing systems were used at costing. 2016 Autumn/Winter Zara baby boys and boys garment collection of a ready to wear and apparel company which locates in İzmir was examined and the results were discussed in the scope of this study.
