The clothing quality, which meets the demands and expectations of customers, depends on
one hand on the aesthetic appearance and the quality of the material used. This can be
regarded as concrete measurements of customers. On the other hand, clothing quality depends
on the properties of produced clothing, which seems to be the crucial criterion of the end
product. Applicable properties of clothing are reflected through the wearing comfort and
clothing behaviour during wearing, i.e., adaptation to body motion and clothing resistance
against acting dynamic loading. This contribution provides an overview of the ease allowance
adopted to provide comfort during body motion. For this purpose the interaction between
body motion and clothing as shell are explained. The contribution then discusses the fit and
allowance for comfort and wearability, and also includes a grounded model development and
detailed overview of various kinds of ease allowance for comfort
