A useful brief can start with plain language. Describe the garment and what the next sample must help you decide, then add the specifications you actually know.
Start without jargon
Write the end use and a short description of the intended outline or surface. If you have a reference, say what should stay similar and what should change. You do not need to invent a GSM.
State hard requirements
Mark composition and care as fixed where they are non-negotiable. Explain prohibited fibres or applicable evidence requirements. Unknown reference data remains a question for Fred.
Keep numerical inputs comparable
Include the weight unit and any measurement basis. Record total and usable width separately. A linear-weight figure needs the width corresponding to that measurement before it can be compared as GSM.
Explain quantity and colour
State the unit and quantity per colour where known. Keep partial estimates labelled as such. Physical colour references may be discussed separately from photographs and screen displays.
Choose a trial purpose
List the collar, facing, pocket, seam or hem questions to be examined. Name the other materials planned for the trial. Ask the pattern maker for sample metreage rather than treating GSM as consumption.
Review and send
The enquiry tool produces English field labels and keeps your free-text wording as entered. Copy or download the entire brief, add your attachments in your own application, and send to Mr Kcal. Opening a message does not prove it was sent.
Correct a brief when the reference changes
If the replacement cutting has another article, finish or colour reference, start a new revision and retain the old one. List the observations that must be repeated and the fields that still need supplier confirmation. A revised brief should identify the change directly; otherwise an earlier preferred surface can accidentally be compared with a quote for a different sample.
Record what a revised brief actually changes
Give a revision its own date or buyer reference and list the changed requirement in plain language. If the usable-width need changes, preserve the old figure and its basis. If the desired hand becomes a preference rather than a hard condition, state that deliberately. Recipients should not have to compare several informal messages to discover which instruction currently applies.
Link each attached sample or photo to the revision it supports. Ask the recipient to identify the article being proposed against that version of the brief, and keep unanswered fields visible. When a reply introduces an exception, decide whether to accept a revised requirement or request another candidate. Do not erase the original constraint just because a convenient sample is available; record who made the change and what still needs to be checked.
