A longer sleeve changes the questions
Turning a short-sleeve T-shirt into a long-sleeve style is more than extending a line on the sketch. The buyer now needs to consider the sleeve shape, opening, intended layering and relationship with the body. Decide whether the product should sit close to the arm, hang loosely or finish in a separately specified cuff. Give the pattern team a reference that shows the intended sleeve and shoulder rather than relying only on the body silhouette.
This creates a clearer fabric enquiry. An everyday long-sleeve basic and a heavyweight fashion top may share a general category while needing different proposals. Describe the job each will perform in the range and keep the two sample discussions separate until there is evidence that one material can support both designs.
Preserve the source targets
The 2026 product planning list includes a combed-cotton long-sleeve crew tee at 150–160 GSM and a separate heavyweight cotton long-sleeve tee at 200–220 GSM. Their numeric garment SKUs do not identify a fabric article. The current SJ-101 catalogue record covers compact combed cotton jersey at 130–170 g/m². It provides a route to discuss for the lighter target, but the wording and complete offered specification still need confirmation.
SJ-102 has higher recorded weights, but it is 95% cotton and 5% elastane. It should not be silently substituted for the heavyweight all-cotton target merely because a weight overlaps. If the requested heavier cotton jersey is not represented by an exact current record, ask for a development proposal. Keep a changed composition or construction visible to the designer and purchasing team.
Compare the sleeve in the garment
Have the sample room record the fabric orientation, pattern revision and assembly choice. Review the garment with the arm relaxed and in the movements relevant to the intended use. Observe the sleeve opening, elbow area, underarm and shoulder relationship. Those observations help the team identify the next development decision; they do not establish a universal performance result.
If a cuff is used, keep its reference separate from the body fabric. Record its dimensions and construction with the accepted sample. A wrist opening that looks right on the first size needs a deliberate review across the intended size range. If the style is designed for layering, evaluate it in that context rather than assuming an isolated fitting answers the layering question.
Review care and decoration in the actual form
Agree the required care evaluation with the responsible technical team and identify the sample used. Keep the body and sleeve observations together so the review does not focus only on overall garment length. A result from a different pattern or material should not become an unexplained approval for the current style. Decide which changes would require another representative trial.
Sleeve artwork also needs its own placement instruction. Give the decoration provider the intended size, location and orientation, and assess the completed sample. A graphic approved for a flat short sleeve may not answer how it should sit on a longer panel. Keep artwork revisions attached to the material and garment records.
Hand over a repeatable long-sleeve brief
For the final enquiry, identify article proposal, composition, finished GSM target, usable width, colour quantities and sample status. Ask the garment team to confirm consumption for its pattern and size mix. Keep commercial confirmation separate from the design review so an accepted sleeve shape is not mistaken for an agreed price or delivery date.
AL KUMAŞ supplies knitted dyed fabric. Long-sleeve garment construction and approval remain part of the separate garment-development programme. A focused brief lets the mill respond to the actual material target and gives the sample room a clear set of decisions to resolve before bulk cloth is ordered.
Source and specification notes
Catalogue figures come from the recorded fabric specifications. Product-planning comparisons retain the source specifications; numeric garment SKUs are not fabric article IDs. General technical references are linked beside the relevant discussion. Development workflow recommendations are editorial guidance.
