Choose a seam or edge finish by the fabric, garment movement and intended appearance. A neat inside finish is useful only when it also works with the material and construction. This guide helps brands specify joining, edge treatment and reinforcement for custom dresses, T-shirts and hoodies.
Seams, edge finishes and reinforcement
A seam describes how materials are assembled; a stitch describes the thread formation. The two terms are related but not interchangeable. Coats’ seam-type reference is useful when discussing construction with a supplier.
| Technique | Purpose and possible application | What to confirm |
|---|---|---|
| 1. Plain seam | A basic joining construction, often used in woven garments. | Seam allowance, stitch specification and how raw edges are finished. |
| 2. Overlocking / overedge stitching | Finishes edges; suitable stitch combinations can also join fabric layers. | Stretch, seam strength, coverage and appearance on the actual fabric. |
| 3. French seam | Encloses raw edges for a neat inside finish, often considered for lightweight woven garments. | Bulk, seam width and suitability for the shape and material. |
| 4. Topstitching | Visible stitching that may secure layers or create a design line. | Thread color, spacing from the edge, stitch length and alignment. |
| 5. Binding / bound edges | Uses a strip to enclose an edge or seam allowance. | Binding material, finished width, stretch and behavior around curves. |
| 6. Blind hemming | Creates a hem with limited visible stitching on the face. | Show-through, puckering and whether the finish suits the fabric. |
| 7. Bartacking | Reinforces selected stress points such as pocket corners or belt loops. | Placement, size and whether reinforcement damages or distorts the material. |
For a T-shirt or hoodie, discuss stretch and recovery instead of choosing a seam solely for its appearance. For a lightweight dress, inspect the inside finish and how seams look through the fabric. No single construction is mandatory for every garment.
Write a construction specification the factory can follow
Mark the seam location on a drawing and identify the required finish. Add thread color, seam allowance, visible stitching position and any approved reference. A process name alone may leave details open to interpretation.
Check the sample inside and outside
- Look for raw edges, skipped stitches, puckering and excess bulk.
- Review seam behavior during movement and stretch where relevant.
- Check consistency at curves, junctions and reinforced areas.
- Agree measurements, tolerances and care requirements.
Is a French seam always better than overlocking?
No. The choice depends on fabric, shape, bulk and intended use. Compare representative samples instead of assuming one finish defines quality.
