How to Brief a Slipper Factory So the First Sample Is Right

A sample that comes back wrong is rarely a factory being careless. It is usually a detail that both sides assumed the other had understood. The fix is unglamorous: specify more before the first cut.

Start from the shelf, not from the factory

Tell the factory where the product will be sold and at what price. A slipper for a discount grocery chain and a slipper for a department store window can look similar in a photo and have nothing in common in construction. Shelf position decides pile weight, sole material and packing more reliably than a reference image does.

The five things worth writing down

1. Upper and lining fabric - not just "cotton" but the weight and finish
2. Sole material and hardness - TPR, EVA, rubber; indoor or outdoor use
3. Sizes and the last - which sizing system, and who the fit is for
4. Packing - polybag, hangtag, gift box, compression; this moves both cost and container volume
5. Test requirements - if your retailer has its own standard, say so in the brief, not after the sample

One page beats a long meeting

If you send nothing else, send a one-page specification plus a photo of a product you consider acceptable. That combination gets a workable first sample far more often than a long call with no written record.

When the sample arrives

Measure it and mark it up. Photograph the changes rather than describing them. Every factory has had the experience of being told "make it softer" and guessing wrong twice; a marked-up sample removes the guess.
