Most people are concerned with how they look and feel in their clothes. Because most people's bodies vary in shape and size, clothes fit individuals differently. Various aspects of body configuration, body size, and posture affect garment fit; therefore, these three factors are concerns for clothing educators and designers. Garments should be designed and constructed to fit the body smoothly, to have the right amount of ease, and to look and feel good. This is difficult to achieve for clothing manufacturers and commercial patternmakers because there are so many different body types. It is impossible to have ready-to-wear clothing that fits every individual perfectly. However, the home sewer has the opportunity to fit the figure accurately using commercial patterns which are sized for average body measurements within a limited number of figure types. The home sewer can make alterations needed to produce correct fit. An understanding of the human figure and different figure types aids in the understanding of pattern alterations. Sheldon, Stevens, and Tucker (1970) used silhouette photography to classify body type, but it is not directly applicable to fitting garments. The original study was 2 conducted in 1940. Croney (1971) stated that of Sheldon's three body types (endomorph, mesomorph, and ectomorph), the mesomorph is used in sizing commercial garments and patterns. However, human bodies fit into one or more of the three categories rather than into this one category. Douty (1968) used somatographs, silhouette photographs taken against a gridded screen, to classify figure types according to body build and posture. The somatograph clearly showed figural and postural variations; therefore, it could be used to view the figure objectively. Much can be learned by visually analyzing body shape, posture, balance, and symmetry, all of which are evident on the somatograph. Colton (1976) suggested that, as people know more about their own.bodies, they find it easier to achieve desired fit in a garment. Somatographs provide a depersonalized representation of the human figure. The sewer should therefore be able to analyze the figure objectively and take accurate body measurements on the somatograph and the self to make correct pattern alterations. With practice, the home sewer should be able to first predict which alterations need to be made to a commercial pattern, and then carry out the alterations necessary to produce a garment that fits the body smoothly and comfortably. Traditional methods of pattern alteration use body 3 circumference and body.length m~asurements as a basis for making personal adjustments, but do not provide any basis for altering dart and seam angles. The somatograph can be used to measure the angles formed by body parts as a basis for pattern alterations, in addition to traditional circumference and length measurements taken directly from the body. The use of angle measurements in combination with traditional circumference and length measurements for pattern alterations should produce a better fitting garment. The bodice area is part of the figure that involves a variety of fitting alterations, because it contains many curves and angles depending on body build and posture (Iowa Horne Economics Association, 1977). Most traditional methods of bodice alteration dO,not include ~ethods for measuring angles, which aid in changing the slope of shoulder seam, side seam, altering the bodice back for rounded shoulders, and increasing or decreasing dart size on bodice front to accomodate the size of the bustline. Measurement of these areas is difficult, if not impossible, to make on the body. Somatographs can be used for angle measurements applied to pattern alterations. Brinson (1977) combined an angle measurement technique and traditional methods of alteration to fit the bodices of basic dress patterns and compared them to bodices altered by traditional methods alone. However, Brinson compared the fit of one person's bodice altered by 4 one method to the fit of a different person's bodice altered by a different method. Pouliot (1980) developed a method for altering pants using graphic somatometry in combination with computerized techniques by using
