4.8 Summary of sizing system

The whole process of developing the sizing system showed the result for the female
aged between 13 and 17years for upper body garment as shown in Table 4.11.
Table 4.11 finally presents the summarized results for the sizing system developed
for teenage girls between 13 and 17years old. From the table the coverage of each
sizing system is high with >95%. The total number of sizes developed to cover
99% of the measured sample is 24. This is the final process of a sizing system in which
the whole flow was demonstrated using a sample data. The success of a size system
can be measured by statistical analysis and wearable analysis. The research conducted
from this chapter has shown the statistical analysis only. The future development will
be conducting the wearable test on the selected data to prove the sizing system is work-
able to be implemented.

4.9 Future trends

This chapter has successfully shown how to conduct analysis of the anthropometric
data in which to develop an accurate garment sizing system for the RTW garment
industry. The purpose of developing a sizing system is to produce garments in sizes
that can accommodate a majority of customers within a set of fixed sizes. Without a
sizing system that is able to generate an appropriate range of sizes for each size des-
ignation, producing good-quality well-fitting garments is impossible, and the overall
objective of mass production cannot be met. When a sizing system is introduced,
researchers must relate it to the understanding of fit. An accurate sizing system must
be built based on actual anthropometric data as the understanding of body sizes and
shapes is the only way to cater to the needs of consumers. The method of producing a
sizing system impacts the efficiency of that sizing system.
The research that is based on theory and practice of sizing system development has
progressively evolved from 1940 to the present. This means that a sizing system needs
a lot of improvement to be efficient. For mass production purposes the sizing system
must be flexible in nature; if there is a need to reduce the number of sizes to make mass
production more efficient, the accommodation rate should not be negotiated. Every
