Why Seam Allowances Matter

In tailoring, the details speak for themselves.

A seam allowance is the small margin of fabric that sits just beyond the stitching line. It’s rarely seen, almost never discussed, but it determines whether a garment can adapt or not. In most modern clothing, this allowance is reduced to the minimum, trimmed away for efficiency. Once the body changes, the garment has nowhere to go.

At Margene, we work against that logic.

Each pair of trousers is designed with deliberately generous seam allowances, built in from the start. Not as an afterthought, but as a structural decision. Because bodies are not static, and fashion shouldn’t pretend they are.

This approach draws from two parallel traditions. The precision of Savile Row tailoring and the pragmatism of Indian garment-making, where fabric is respected, preserved, and expected to last. With this construction, trousers can be altered by up to two sizes over time, quietly extending their relevance, wearability, and life.

When paired with Alter, our complimentary lifetime alterations service, seam allowance becomes more than a technical detail. It becomes a way of thinking. About longevity. About designing garments that respond to real lives, rather than resisting them.

So when a pair of trousers fits just right, now or years later, it isn’t coincidence. It’s intention, built into the inside.
