Show the starting point
Include a sketch, reference image or existing product direction. Mark what you want to retain and what you want to change. Clear annotations are often more useful than a long folder of unrelated images.
List the practical details
Describe the intended shape, dimensions, handle, pattern, colours, lining and branding. If a specification is undecided, say so rather than leaving the supplier to guess.
Explain the collection context
Share your intended market, order quantity, target budget, packaging requirements and delivery destination. These details help frame the feasibility and quotation discussion.
Agree what happens next
Ask for product-specific MOQ, sample costs, revision scope and an estimated schedule. Confirm the final sample and written order terms before bulk production.
