Putting on and taking off clothes

[iLimix]

I try to find out if he is wearing a vest and if so, to take it off and if not, to put on a specific one
However, it doesn’t quite work

                    local playerPed = GetPlayerPed(-1)

                    if IsPedComponentVariationValid(playerPed, 9, 6, 0) then
                        print("Valid component variation")
                        ClearPedProp(playerPed, 9)
                    else
                        print("Invalid component variation")
                        SetPedComponentVariation(playerPed, 9, 6, 0, 0)
                    end
