Due to the inflow of the western culture since the 19th century, female skirts and jackets have been changed considerably in detail though their basic composition was maintained. The analysis on female jackets from the start of the modern period to 1960s has been undertaken with artefacts as well as reports and research dissertations related to them. For period appraisal, analysis was divided into several periods which are from 1890s to 1910s, and every 10 years afterwards. As a result, aspects for the appraisal in each period was found. Aspects for period appraisal in modern jackets can be a change in total length and side length, a change in shape of the sleeves (from straight to round), a change in width, and a difference in closed shape of the collars. Material and color can be another aspect which shows fashionable material or new materials (man-made textile or nylon) of each period, color combination of surface and lining material as well as other parts of the jacket, use of a stiffener made with net or sheer textiles. Research using books and archives is important for the appraisal of the garment artifact. However, most of all, one should have the attitude of examining the artifacts frequently in order to achieve deeper understanding and an eye for accurate appraisal.
