Another common question about waxed cotton is how much it stretches. While the answer will depend on the type of wax used and the garment. In general, waxed cotton will stretch 1 or 2 cm with wear, but this doesn't mean it's a flexible garment: waxed cotton is stiff, and the stretch will happen slowly with wear. If you're looking for stretchy fabric, then you may want to consider one of several types of synthetic fabrics that do.
