What kind of finishing does having no stitching on the shoulder and armhole lines refer to?
This question seeks to confirm the specific appearance and purpose after seeing the phrase stating that there is no stitching in the t-shirt's detailed description.
It is a finish that conceals visible stitching lines to neatly and cleanly arrange the surface running from the shoulder to the sleeve.
Stitching refers to visible sewing stitches placed on the outside to join or secure fabric. Typically, t-shirts are finished with outer topstitching around the shoulder line and the armhole where the sleeve connects to maintain shape and press the seams flat.
INSILENCE's 수피마 코튼 프리미엄 티셔츠 BLACK has omitted visible outer stitching at these shoulder and armhole areas[1]. When thread lines are not left on the outer surface, the area around the seam looks much cleaner, and the flow falling from the shoulder line down the sleeve connects smoothly without interruption.

How the inner seam allowances are secured instead of having visible stitching on the outside has not yet been confirmed from official materials.
