Why does the collar look nice on the sample but look different after washing?
Fabric, interfacing and stitching work together. It is risky to decide on the collar drawing alone without seeing these three in the real product and the target care condition. We use the same approach for the headline.
Review the design and sample processBalance between structure and use
Collar and cuff together affect the facial expression and wearing comfort of the shirt. A structure that is too stiff can create an unnatural break in lightweight fabric; Insufficient support may not maintain the targeted form.
Points to consider when choosing interlining
Interlining is not selected only by the weight label. Adhesion behavior, risk of leaving marks on the fabric surface, post-washing behavior and its relationship with edge stitching should be tested on real material.
- Fabric weight and surface
- Target collar form
- Care and washing expectation
- Structure compatibility with front placket and cuff

Symmetry, corners and underwire
Collar ends, foot height, cuff corners and buttonhole-button positions are measurable control points. The need for removable or fixed underwire is determined by the collar shape and end use.
Structural verification in sample

Can the same interlining be used on all fabrics?
No. Fabric weight, surface, maintenance process and targeted attitude may require different interfacing trials.
Should there be underwire on every neckline?
No. Underwire is a structural detail chosen according to the collar form and purpose of use.
