A Custom T-Shirt Should Not Start With the Artwork

A Custom T-Shirt Should Not Start With the Artwork

  • Printing cannot correct an unstable neckline, excessive shrinkage or poorly balanced proportions.
  • Before decoration is applied, KELLOGG defines the finished GSM, shoulder width, body length, sleeve shape, collar construction and expected wash behaviour.
  • Artwork, printing and embroidery are developed only after the base T-shirt has been approved for fit, structure and dimensional stability →.

Custom T-Shirt Fit Development

We develop oversized, boxy and relaxed T-shirt fits by balancing shoulder width, chest volume, body length, sleeve shape and fabric structure.

Oversized Fit

Dropped shoulders, increased chest width and fuller sleeves create a balanced oversized T-shirt fit with controlled body length and modern proportions.

Boxy Fit

A wider body, structured shoulders and controlled length create a boxy T-shirt fit with balanced sleeves, clean lines and compact proportions.

Relaxed Fit

Balanced shoulders, moderate chest width and natural sleeves create a relaxed T-shirt fit with comfortable movement, controlled length and everyday versatility.

Size Grading Without Losing the Intended Fit

T-Shirt Construction That Protects Fit and Shape

Heavyweight and oversized T-shirts place additional stress on the neckline, shoulder seams and garment structure. Construction must be developed around the fabric weight and intended silhouette.

Collar Recovery

  • Collar rib width and stretch ratio control neckline recovery.
  • They help heavyweight T-shirts retain their shape after washing.

Shoulder Stabilisation

  • Shoulder taping and reinforced seams control fabric stretch.
  • They help heavyweight T-shirts maintain stable shoulder proportions after repeated wear.

Seam & Hem Control

  • Stitch type and seam allowance are adjusted for fabric thickness.
  • They create cleaner hems and stronger heavyweight T-shirt construction.

Side-Seam Stability

  • Fabric grain and cutting alignment control side-seam twisting during production.
  • They improve overall T-shirt shape stability after repeated washing.

How We Evaluate a Custom T-Shirt Before Bulk Production

Before bulk production, the approved T-shirt is evaluated for fit, neckline performance, dimensional stability and decoration compatibility.

The Approved T-Shirt Sample Is Not a Suggestion

The Approved T-Shirt Sample Is Not a Suggestion

  • The approved T-shirt sample establishes the finished measurements, fabric weight, neckline construction, stitching, wash result and decoration standard.
  • Bulk production is checked against this approved reference, including collar shape, shoulder proportion, garment length, shrinkage and artwork placement.
  • The same specifications and physical references are retained to improve consistency across repeat orders.
