1. What Is a Seam?
A seam is where two pieces of fabric are joined together by stitching. Seams are responsible for:
-
Holding the garment together
-
Affecting comfort and stretch
-
Contributing to the shape and structure
-
Influencing the inside/outside finish of the garment
At HEM APPAREL, we choose seam types based on the garment’s function, fabric, and final aesthetic.
2. Common Seam Types and Their Uses
| Seam Type | Description | Best For |
|---|---|---|
| Plain Seam | Basic edge-to-edge stitch, pressed open | Most T-shirts, shirts |
| French Seam | Encloses raw edge inside seam | Delicate fabrics, dresses |
| Flat-Felled Seam | Fully enclosed, double-stitched seam | Jeans, workwear, rugged outerwear |
| Bound Seam | Edged with tape or bias binding | Jackets, sportswear |
| Lapped Seam | One piece overlaps another | Denim, structured pieces |
| Flatlock Seam | No seam allowance, lays flat on both sides | Performancewear, activewear |
3. Seam Type by Product Category
| Product | Common Seam Types |
|---|---|
| T-shirts | Plain seam + overlocked edges |
| Jeans | Flat-felled + topstitch |
| Leggings | Flatlock seam for zero bulk |
| Outerwear Jacket | Bound seam for cleaner finish |
| Dresses (sheer) | French seam for elegance |
A wrong seam choice can lead to discomfort, unraveling, or a bulky finish — especially with stretchy or delicate fabrics.
4. Seams and Customer Experience
The seam affects how a garment feels when worn:
-
Flat seams = less irritation (great for activewear)
-
Reinforced seams = better durability (good for uniforms)
-
Topstitched seams = add design value (great for streetwear)
Seam details are often unnoticed by customers — until they become a problem.
5. Tips for Communicating Seam Preferences
When briefing your manufacturer:
✅ Use photos of seams you like
✅ Specify exposed or hidden seams
✅ Mention if it needs reinforcement (e.g., shoulder tape, double stitch)
✅ Ask for inside-out photos of samples if you're unsure
At HEM APPAREL, we advise brands on seam options that match both cost and design intent.
🔚 Conclusion
Seams are more than just structure — they’re silent contributors to quality, comfort, and perception. Choose them intentionally, and your garment will speak volumes without saying a word.
