For casual pants manufacturer orders, minimums typically start from 100 pieces per colour and style with full size runs inside that number. Pricing depends on fabric type and weight, stretch content, pocket and panel complexity, print or embellishment coverage, chosen trims and packaging. That 100-piece level is designed to absorb pattern development, sampling and private-label setup in a fair way. As volume increases, unit costs usually improve thanks to better fabric utilisation, cutting efficiency, trim usage and decoration economics.
