DEVELOPMENT PROCESS

How Custom Seamless Development Works

The confirmed flow from our seamless guides — specification first, then knitting structure, sample, fit approval and bulk.

Step 11

Reference, size range and quantity

Send reference images or sketches, your size range and target quantity per style and color — seamless starts on a knitting machine, so yarn purchasing and machine scheduling follow your numbers.

Canvas / steel / glass
Step 22

Yarn and knitting structure

Composition, denier, gauge and program zones — compression, mesh, texture — are confirmed before any sample is knitted.

Home / work / travel
Step 33

Sampling

Your style is knitted, dyed and finished as a physical sample for fit and opacity review — checked per colorway, on the body.

Shipping / returns / care
Step 44

Fit approval and revisions

Fit is controlled by the knit program, not scissors; one revision round is normal and each change is a development change, not a grading change.

Step 55

Bulk production

Bulk runs 20–30 days after sample approval and deposit, with in-line QC during knitting and finishing.

SEAMLESS MOQ

Seamless MOQ

Seamless minimums follow garment structure, not a single number — the confirmed rules from our seamless manufacturing guide.

Long styles1

From ~500 pcs per color per size

Applies to longer seamless garments such as leggings and full-length unitards. The final production plan is confirmed after reviewing design, materials, colors and size range.

Canvas / steel / glass
Short styles2

From ~1,000 pcs per color per size

Applies to shorter styles such as tanks and sports bras, where knitting time per garment is lower but machine scheduling still sets the floor.

Structure first3

MOQ depends on the garment

Design complexity, color count and size requirements move the number — quoted per project before you commit.
