Two scrunchies in the same fabric, the same colour and the same finished size can look like completely different products.
The gather ratio
A scrunchie is a tube of fabric bunched along a shorter loop of elastic. The ratio between those two lengths is the gather ratio.
At around three to one you get a full, deep, generous ring. At barely more than one to one you get a flat band with a visible seam. Everything in between is a sliding scale of how expensive the thing looks.
Why it disappears from quotes
Because it is pure fabric. Halving the gather ratio halves the fabric in the product and is invisible on any specification sheet that lists fibre, colour and size.
It is the single most effective way to make a scrunchie cheaper, and the single most visible in a photograph.
Elastic width plays into it
A wide, full scrunchie on a thin elastic collapses into itself and loses the shape anyway. Bigger sizes need wider elastic to hold the gather out.
This is why simply asking for “oversized” is not enough — an XL on a narrow elastic is a lot of fabric with nothing supporting it.
How to compare two suppliers
Ask both for the gather ratio and the elastic width, in numbers, and ask for a physical sample of each.
Put the two on a wrist next to each other. It takes thirty seconds and it is the whole decision.
