The purpose of this study was to review materials that could provide basic data about sports brassieres. In this study, 486 sports brassieres were collected online from 31 brands between November 2015 and February 2016. First, the comparison of compression and encapsulation in sports brassieres identified many different styles. The characteristics of compression brassieres included a cut cup, the front center height of a full cup, round neckline, short front hem, all in one shoulder strap with a patterned racerback design, all in one closure, no wire, and separation cup styles. The characteristics of encapsulation brassieres included a V-shape neckline, mixed round shoulder strap design, back closure, and all in one cup. Second, the comparison of domestic and international sports brassieres sorted the items differently. The characteristics of domestic products included compression brassieres, non-cut cup, the front center height of a full cup, round neckline, short front hem, an all in one shoulder strap with a patterned round design, all in one closure, no wire, and a separation cup. The characteristics of international products included a cut up, racerback shoulder strap design, and an all in one cup. Third, the analysis of domestic and international sports brassieres sizes found that six options were available for domestic compression sports brassieres and nine sizes were available for international products. Domestic encapsulation sports brassieres offered five under bust sizes and five cup sizes. International products offered eight under bust sizes and sixteen cup sizes.
