The Apparel Merchandising Process: From Line Plan to Line Release

A clothing line does not appear fully formed. It moves through a defined pipeline, from a plan on paper to real merchandise on a rail, and each stage narrows the possibilities until only sellable styles remain. The exact steps vary by company, product type, and technology, but the backbone is consistent. Understanding it tells you where your design decisions get locked in, and where the tech pack takes over.

What a "line" actually is

A product line is a group of related merchandise built for one target market. The word is used loosely: it can mean a firm's entire offering (say, men's shirts), or a specific sub-group within that. Everything below is about turning that idea into product.
