I'm reaching out regarding a mock-up I've created for a tracksuit that includes both a top and pants. I'm interested in discussing potential materials that would be suitable for this tracksuit, as well as the associated costs for creating a sample. In particular, I'd like to ensure the pants have the desired cuff cut on the legs that I have in mind. Could you provide details on the fabric options available, as well as the pricing for the sample production? Looking forward to your response.
