A method for establishing a compression level to a human limb or body part (8) by a compression garment is shown, the garment consisting of or including a bandage having at least one closing part (5), which closing part is securable on the garment in a position wherein the bandage is fully or partly wrapped around said limb or body part to establish said pressure level, the method including - a first step of wrapping the bandage around the limb or body part and provisionally securing it in a first position that holds the compression garment on the limb or body part without applying a compression level to said limb or body part； - a second step of applying a tab (10) with an adhesive or attaching mechanism to the garment, the tab abutting the terminal edge of the closing part； - a third step of releasing the closing part from its provisionally secured position and wrapping the bandage part further around the limb or body part, using the length of the tab as a marking for a safe compression level range； and - a fourth step of securing the closing part to the garment at a second position within the safe compression level range.
