Start with length set and fullness
Bundle shoppers usually know the texture first, then compare length sets. A 16/18/20 body wave bundle set is usually easier to keep full than a longer 24/26/28 set because longer bundles carry less weft per bundle. This is why strong bundle pages should explain fullness, leave-out, closure coverage, and frontal coverage before pushing a customer into checkout. The goal is to help the shopper understand whether the selected package can complete the install they have in mind.
