The sizes have been created by the Hogeschool Ghent because the current sizes are no longer applicable. This is part of a plan to change clothing sizes throughout the EU. During 2012 the Hogeschool Ghent did a national study where people across the nation were measured and new sizes were introduced due to the results. The last time this type of study took place was during 1990, but the average Belgian has grown two centimeters since then. The average body of a female has changed from that of an hourglass into an H-model, but with wide hips.
