In order to study the wearing comfort of pressure for tight‐fit clothing, the sensation of wearing pressure and the other related sensations have been assessed for knit garments, which have different sizes and fabrics which have different extensibilities, by developing a wearing experimental procedure. Using factor analysis with principal factor solutions and rotated by the Varimax method, we obtained relevant factor matrices about the subjective assessment. At the same time, objective clothing pressure, fabric extensibility and garment fitness have been measured. Regression analysis showed that the garment fitness and fabric extensibility had great predictive power for the subjective pressure assessment.
