The reliability means, “the measure of unanticipated interruptions during the customer use”, that normally rises from the unexpected failures. In productions’ phase the manufacturing industries uses the reliability test that maximizes the opportunities for observing an unexpected failure. Durability is “an ability of the products to last long without signification deterioration,” which has a capability of maintaining the serviceability of a structure over a specified time with required safety that corresponding characteristics, and serviceability.
The durability of products is one of the difficult aspects for most designers, developers, or builders for sustainability, because there are no standard or widely accepted methodologies have been used for evaluating the durability for the products. Throughout the world, many products such as house hold appliances to furniture to clothing to footwear, and automobiles’ parts are dumped every year, and many of them are thrown away prematurely, obsoletely, or technologically outdated, non-repairable or non- upgradable; therefore the durability concepts have been increasingly regarded as a disposal in manufacturing.
The reliability and the durability rely on the internal qualification tests, because both of them are calculated from the basic principles, as well as the mathematical models, which brings similar testing results for the both (durability and reliability); therefore it is hard to ...

...ting are intertwined in customized clothing.
Consumers are categorized into market segments of individuals sharing common patterns of criteria in the acquisition of their clothes. Users of customized clothes form such a market segment, although not a homogeneous one, which shares common interest in quality.
