A Hong Kong finish is a seam finish in which each raw edge of the seam allowances is bound separately with a narrow bias strip of lightweight fabric, then the allowances are pressed open. The bound edges cannot fray, lie flat, and look deliberately beautiful — which is the point: the finish is the signature inside of unlined jackets, trousers and skirts in quality ready-to-wear and couture, where the inside of the garment is on show. It is named for the tailoring workshops of Hong Kong, long famed for fine unlined work.
How It Is Sewn
A bias strip about 1 inch (2.5 cm) wide — often silk, lawn or a decorative lining fabric — is stitched to the right side of each raw allowance edge, wrapped over the edge to the underside, and secured by stitching in the ditch from the right side, or by hand. The seam itself is sewn and pressed open in the usual way, each side now carrying its neat bound edge. Because the binding is bias, it follows curved allowances such as armholes without puckering.

Where It Belongs
Hong Kong finishing is chosen when a garment is unlined or half-lined and the seams will be seen, and when fabric frays too much for a clean finish but a serged edge would look cheap against the garment's quality. It adds time — every allowance of every seam is bound — so it signals a deliberate standard of make. It is one of the seam finishes grouped on this site with bound, welt, clean and serged finishes for comparison.
The finish rewards unhurried work. Strips are cut with a rotary cutter for even width, sewn with a slightly loosened top tension so the wrap does not pucker, and pressed from the underside over a seam roll so the binding's edge stays knife-sharp. Traditional tailoring hides one more courtesy inside: the binding is often cut from the jacket's own lining remnants or a Liberty-style print, so the inside carries a private detail only the wearer and their tailor will ever see — a small signature of a garment made to be kept.
FAQs
- Is a Hong Kong finish the same as a bound seam?
- It is a type of bound finish: specifically, each seam allowance is bound separately and the seam pressed open, rather than both allowances bound together as one package.
- Why use bias strips for the binding?
- Bias stretches and curves, so it wraps an edge — including curved allowances like armholes — smoothly without puckering, and adds almost no bulk.
- Can a Hong Kong finish be done by machine?
- Mostly yes: the strip is machine-stitched and caught by stitching in the ditch. Couture work often finishes the wrap by hand for an invisible result.
