First wrap double-sided sticky tape around a roller to pick up bits from clothes. Than roll over the areas covered with hair. For bigger areas use a bigger roller!
If you have Marigolds, moisten those and “stroke” the hair covered items. That works well too.
When my cat starts loosing his fur, I get him in the garden and stroke him with the Marigolds, that releases all the loose fur, which comes in handy for the birds nesting, so don’t thow it away!
