Definition
When cutting, seam allowances are planned in addition to the actual cutting dimensions. They enable sewing, overcasting and - depending on the width - later changes.
In simple words
In the finished garment, the seam allowance is usually on the inside and remains invisible. Nevertheless, it reveals a lot about processing and changeability. Additions that are cut back very tightly appear slim, but leave little room for expansion. Wider additions can be deliberately left as a reserve with high-quality tailoring.
What to pay attention to
- Check trousers, skirts and jackets to see whether there is room for alterations on important seams.
- Check whether the edges are neatly finished and not frayed.
- Note that wide allowances can press through fine fabrics.
Common misconceptions
The seam allowance is not the seam itself. It is the material outside the seam line and influences processing and changeability.
ESKYNA mnemonic
What lies on the inside next to the seam often determines how long a garment remains adjustable.
