Before checkout

Why customers hesitate before they buy

Size uncertainty adds work at the exact moment the customer should feel ready.

Will this fit me?

Size charts are often too general.

Does this model run small?

The brand alone does not say enough.

Do I need to measure myself?

Extra steps create friction.

What if I choose wrong?

Uncertainty weakens purchase confidence.

Item-level guidance

Same customer.
Same brand.
Different recommendation.

The right size depends on model, cut, fabric, category and how the customer likes the item to fit.
