A measurement system for a wearable item comprising a capacitive pressure sensing system (5) including a plurality of capacitive sensors (6) comprising a deformable insulator layer (32a, 32b) and at least first and second electrodes (30a, 30b, 30c) on opposed sides of the deformable insulator layer, the capacitive sensors arranged in a distributed manner over a surface for covering a body part subject to impact. The capacitive sensors comprise first and second deformable insulator layers (32a, 32b) separated by a third electrode (32c), the first insulator layer having an elastic modulus that is different or the same to the elastic modulus of the second insulator layer, the capacitive sensors configured to measure a pressure applied on a major surface of the sensor transverse to the stacking direction of the electrodes and deformable insulator layers.
