Unlined and Half-Lined Summer Jackets: What to Put in the MTM Brief

Unlined and half-lined jackets are lighter for summer and warm markets. But the inside of the jacket is now visible, so the brief has to say how it should look. This post lists what to specify on an MTM or private-label order. We do not claim cooling performance or invent fabric weights — you choose the cloth and we follow the finish notes.

What becomes visible

• Seam finishes on the body and sleeves

• Pocket bags

• Front facings

• Shoulder and chest structure

• Label positions when there is no full lining to hide them

A Hong Kong MTM shop selling summer odd jackets to clients who travel often will see these details in every fitting-room mirror. If the brief is silent, the plant fills gaps with its default — and defaults rarely match a house look.

What to specify

• Lining level: unlined, quarter-lined or half-lined (and sleeve lining yes or no)

• Seam finish: state your preference, for example bound seams, with a photo

• Pocket bags: cloth or lining fabric

• Facings: width and finish, with a reference

• Construction: soft construction choice, with a reference jacket

• Labels: where they sit when there is no full lining

Same list, numbered

1. Lining level

2. Seam finish

3. Pocket bags

4. Facings

5. Construction

6. Label position

• Spec: Lining level · Example note to plant: Half-lined body, sleeve lined · Photo needed?: Yes — open jacket

• Spec: Seam finish · Example note to plant: Bound seams as reference · Photo needed?: Yes — inside close-up

• Spec: Pocket bags · Example note to plant: Self-cloth bags · Photo needed?: Optional

• Spec: Facings · Example note to plant: Match reference width · Photo needed?: Yes

• Spec: Labels · Example note to plant: Centre back neck + side seam care · Photo needed?: Artwork file

Same table as a list

• Lining level — e.g. half-lined body, sleeve lined — open-jacket photo

• Seam finish — bound seams as reference — inside close-up

• Pocket bags — self-cloth or lining fabric

• Facings — match reference width

• Labels — positions + artwork

Approve on the physical sample

Inside finish is hard to judge in a photo alone. Approve on the physical sample when you can, then use it as the reference for later orders. If the sample must ship before a fitter sees it, require the open-jacket photo set below and confirm changes in writing before production.

Photo set for inside approval

1. Jacket open, front facing visible

2. Inside back and side seams

3. Pocket bag close-up

4. Sleeve lining (if any)

5. Label positions

Order tracks and clocks

• MTM from 1 piece — individual client orders and trial pieces

• Bulk from 50 pieces per style — private-label and core-style runs

• Sample: 7–14 days

• Production: 14–21 days

Both clocks count from the point measurements, cloth and construction are locked. Production days are not delivery days; shipping is separate and is confirmed in writing on WhatsApp +65 8013 8838.

A Singapore boutique preparing a house unlined linen-blend odd jacket typically locks MTM from 1 for the house model, seals the inside finish on the sample, then opens bulk from 50 for the size run. Restate lining level and seam finish on the bulk brief — do not assume they carry over from a voice note.

FAQ

Do you claim a cooler garment because it is unlined? No. Unlined and half-lined are construction choices. Cloth and climate are the client's and the shop's call.

Can I start with one piece? Yes — MTM from 1. Bulk from 50 per style after the sample is sealed.

When does the sample clock start? After measurements, cloth and construction (including lining level and seam finish) are locked.
