I would like to build a licensing map, i.e. who manufactures for which brand.
I'm confused. The title to your entry was "List of Designer Lines and their Manufacturing & Production Sources" but now you're talking about licensing. In the apparel industry, licensing means you're buying the rights to use the designer's name for a product you already manufacture (for example, sunglasses) At best, the designer stipulates the quality levels, criteria or colors that fit with their image. The licensee never delivers the product TO the designer but sells it on their own, again according to venues that were established in the licensing agreement.
Licensing is distinctly different from contracting iow, "manufacturing and production sources". The latter is done strictly to order. The designer or staff does everything or at the very least, they have the contractor do the work under their auspices. Likewise, the goods are delivered TO the designer or an agent (distribution center) and shipped to customers who placed orders.
Licensing is a public affair, often with much fan-fare. Contracts are understandably coveted and it's easy to discern who's garnered one. Not so with contractors (production and manufacturing) making the goods (usually clothes) to order. This is one of a designers most tightly held secrets. They don't want it known who makes their patterns or sews their products or even who sells them their fabric and buttons because it'd be easier to compete with them in the marketplace. If you wanted to compete with RL purple label, who better than to hire their pattern maker and contract house? See what I mean? You won't find that information broadcast.
I'm a service provider in the garment industry. We -for the most part- are not allowed to say who we work for. If we do say, you can bet money they are either no longer a client or we were doing something along the lines of commodities (tees etc) nothing specialized. My clients are very paranoid. Even amongst ourselves (among colleagues) we don't mention who we work for. It's considered very bad form to even ask. Rude in fact. Before anyone comes over (colleague or new client) we put everything away.
I wish you well with your thread but I don't think you'll uncover many production sources. I could tell you about some designers but then I'd have to kill you.
