美国采购需求：男装、裤子

I'm looking for custom sweatpants mock-ups to evaluate different designs and styles. Ideally, I want samples that showcase various colors, materials, and fits to help me visualize the end product. Could you provide me with some mock-up options? It would be great to see how your sweatpants can be tailored to meet specific branding needs. If you have any previous designs or templates that can guide this process, please include those as well!
