Tailor collar jacket 4 Sewing Patterns | DRCOS Patterns & How To Make

This is a sewing pattern and construction guide for a slightly long, four-button jacket design commonly used in cosplay costumes. The waistline is gently shaped to create a clean and well-defined silhouette.

The pattern can be arranged for different styles, such as lowering the collar to create a blazer suitable for school uniform designs. It is a flexible base pattern that allows easy customization depending on your project.

The lining and facings are simplified compared to standard jackets, making the construction easier. However, this pattern is still considered advanced, and basic to intermediate sewing skills are required.

As this pattern is simplified specifically for cosplay costumes, we recommend adjusting the lining structure if you plan to make a jacket for everyday wear. Modifying the pattern lines will result in a more refined finish.

The sleeves are fully structured two-piece tailored sleeves with curved seams. Easing is used to create a natural rounded shape, which requires careful sewing. Please note that dart placements differ from standard jacket patterns.

After printing, align the indicated joining lines, assemble the sheets, and cut out the pattern pieces. Seam allowances are included, so the pattern can be used as-is.

(1) Apply interfacing to all required parts, then sew all darts and press them toward the correct direction with an iron.

(2) Attach the dummy pocket and flap to the designated position on the front body.

*If you plan to make a functional pocket, prepare and sew the pocket at this stage.

(3) Sew the outer fabric, facing, and lining together to form the body shape, then attach the collar pieces to each part.

*Make small notches in tight curves around the collar and lining to allow smooth turning.

(4) Sew all sections except the hem, then turn the garment right side out.

*Lightly press the hem in advance to make the final finishing easier.

(5) Sew the sleeves and attach them to the body.

*Sleeve caps must be eased in using hand basting; skipping this step will prevent proper sleeve attachment.

(6) Finish the hem by hand-stitching to close the opening.

*Areas that tend to shift during sewing should be temporarily secured with hand basting to achieve clean and smooth lines.
