A device for applying compression treatment to a part of a wearers body has an inner face for being placed adjacent to the part of the wearers body in use and an outer face opposite the inner face. The device includes a pressure applicator to apply compression to the wearers body part when the device is placed on the wearers body part. First and second fastener elements are mounted on the device. The second fastener element is adapted for releasably connecting to the first fastener element for use in holding the device on the wearers body part. A visual indicator associated with the second fastener element is adapted to show where to engage the first fastener element with the second fastener element. The visual indicator is adapted to wear upon repeated connection and disconnection of the first and second fastener elements so that the visual indicator fades over time.
