What is the 'haeri tape finish' mentioned in the description?
This question is asked when reading a T-shirt product description and wondering specifically what role the sewing method known as haeri tape plays.
The haeri tape finish is a method in which the edge of the fabric is wrapped with a separate fabric tape and stitched to neaten the seam and prevent stretching.
Haeri refers to a sewing technique where the seam allowance or the edge of the fabric is bound and stitched with a thin strip-shaped cloth. It cleanly conceals the inside of the garment to keep threads from fraying, while the layered fabric adds support to firmly hold the shape.
THREE TO EIGHTY applied this haeri tape finish to the inside of the T-shirt's neckline[1]. This method reduces shape distortion along the neckline, which stretches most easily when putting on and taking off a T-shirt, and finishes the seam touching the skin flat and softly.

The detailed fabric composition and width of the tape fabric used for the haeri tape have not yet been confirmed in official materials.
