We examined the validity of application of moiré topography to determine the amount of clearance distances between body surface and weared clothings. The subjects tested were one adult female and a replica of her torso made symmetrically on both sides. The test clothing were one no ease sample made from true development of real body surface and three samples which differ in grades and types of ease. The shapes of each subject before and after putting on test clothings were measured by moiré topography. The position and the amount of clearance are thus determined. The X-ray fluoscopic observation was also made for reference to the torso replica. The results were as follows : 1) The clearance distances show different values depend on the measuring points of the body and on the amount of ease of clothings. 2) The validity to use moiré topography is confirmed, because the results from moire topography and X-ray observation have been similar. 3) The distribution of clearance distances for live body is observed almost the same as that for the replica. By this and above facts, moiré topography may well give reliable results for the clearance measurement of live body, as long as the experimental conditions are strictly regulated.
