The objectives of this study were 1) to investigate the clothing needs of physically han- dicapped children, 2) to present the basic data to make the slacks patterns which meet the specific needs of physically handicapped children under study. Questionnaires were administered to 38 mothers of handicapped children and the subjects for the wear test were five handicapped children using wheelchair. The fabrics used for slacks wear test were: muslin woven with cotton, stretchable jean woven and double jersey knitted with cotton and polyester fabrics. The results obtained from this study were as follows: 1) The majority of the handicapped children were wearing ready·made-garments and their mothers considered the fabric elasticity first. 2) The slacks wear test indicated that the slacks ease of 8 cm should be added above the natural waist line in the back for the wheelchair bound children. 3) In a sitting posture on the wheelchair, $3~4$ cm should be cut below the natural waist line in the front but in a standing posture, $1~2$ cm should be cut below the natural waist line in the front. 4) The double jersey (cotton/polyester) slacks was highly estimated of ease ana length of slacks in a sitting posture. The stretchable jean (cotton/spandex) slacks was estimated high of appearance but muslin slacks (cotton) was less estimated of ease and appearance of slacks.
