Abstract:

A key factor affecting consumer satisfaction with sportswear is garment fit and in turn comfort. Currently there is a large volume of research regarding the use of 3D body scanning and its incorporation into sizing systems and garment development. It is a common belief that to maximise the fit of a garment, both size and form must be considered, however, some companies still base their sizing systems on a single body type/ shape. This paper aimed to categorise female body form into different shapes through the use of two evaluation techniques:
1) Determination of body shape according to pre-defined ratio rules for the width of the chest, waist and hips (silhouette shape),
2) Determination of body shape according to ratio rules based on the chest, waist and hip circumferences,
Each method was used to evaluate 300 European scans, which were collected using a TC2 scanner.
The results from both analysis methods identified that over 95% of the population could be categorised into one of 4 body types. When using analysis method 1 (silhouette shape) the 4 dominant forms were hourglass (11%), bottom heavy hourglass (30%), rectangle (5%) and spoon (49%). Whereas, through the use of method 2 the forms identified were hourglass (36%), soft hourglass (34%), spoon (10%) and rectangle (15%). To further analyse the results, a shape analysis was conducted by comparing width and depth (front to back) measurement at each location. These results identified large variations in form within shape categories when using the single width measurement. The variation in shape was significantly reduced when circumference measurements were used. Based on the results from method 2, the relationship between size and shape was examined, identifying that as size increases the chest - waist and waist - hip ratio needs to decrease. These ratio changes result in a gradual change from hourglass to rectangle shape. As a result a better fit could be potentially achieved for up to 25% of the target population.
