The relationship between the swelling on the lower half of the body and the current purchasing trends of “support knee-high socks (SKS)'' were examined by a Net questionnaire for 1425 women's consumers from 10 to 60 years old. Some 70.7% of the whole participants were office workers, full-time house-wives, and part-time workers from 20 to 40 years old. 79.3% of participants, who had awareness of their swelling, were aware of the swelling in the lower half of the body such as calf, ankle and instep. A growing awareness of the swelling was closely related to the total time of walking and sitting. The swelling aware participants were significantly longer in total time than those who are less aware. 44.8% of them have bought SKS as confidently hoped that the swelling would be relieved. However, 34.4% of them have not bought SKS, which seemed ineffective against the swelling for the reason. The swelling should be relieved in order to reduce the load of the body.On the matter, here we showed a few basic guidelines for the development of comfort SKS by using not only the questionnaire but also the physiological data.

Dimensions of “one-size-fits-all” clothing are not specified in the Japanese Industrial Standards, and the actual sizes are unclear.The present study investigated the specifics of women's one-size-fits-all mail-order clothing. The one-size-fits-all represented 1.5% of the women's clothing available from 10 mail-order companies, of which 337 items of the clothing for upper body were selected for further study. A majority of the clothes (54.0%) were knitted, and thus possessed considerable elasticity and were capable of adapting to the body shape of the wearer even if the size was unclear. However, despite being labeled as one-size-fits-all, 89.0% of the items were based on medium size dimensions and thus could only conform to a limited range of body shapes.Furthermore, despite being for sale by mail-order, a range of the actual body measurements and/or the item's finished sizes were not always clearly stated. It is therefore necessary to confirm the dimensions of clothes prior to purchasing.
