文(wen)胸(xiong)是女(nv)人(ren)的(de)第二層(ceng)肌(ji)膚，其功(gong)能(neng)主要是為(wei)了幫(bang)助女(nv)性(xing)乳房提(ti)供外(wai)部支撐(cheng)，避免造成疼(teng)痛不適，這就(jiu)意(yi)味著(zhu)文胸(xiong)(xiong)(xiong)必須有足夠的(de)舒適性(xing)以(yi)(yi)及支撐力(li)。因(yin)此，女性(xing)在(zai)選購(gou)適合自己(ji)的(de)文胸(xiong)(xiong)(xiong)之前，還需要(yao)學會(hui)如(ru)何(he)量罩(zhao)杯，以(yi)(yi)及分清楚胸(xiong)(xiong)(xiong)罩(zhao)尺(chi)寸(cun)和罩(zhao)杯尺(chi)寸(cun)的(de)區別。胸(xiong)(xiong)(xiong)圍通常是指(zhi)沿(yan)女性(xing)乳頭繞(rao)胸(xiong)(xiong)(xiong)一(yi)周(zhou)的(de)長度，而(er)胸(xiong)(xiong)(xiong)罩(zhao)尺(chi)寸(cun)指(zhi)的(de)是下胸(xiong)(xiong)(xiong)圍繞(rao)一(yi)周(zhou)的(de)尺(chi)寸(cun)，罩(zhao)杯尺(chi)寸(cun)即(ji)胸(xiong)(xiong)(xiong)圍減(jian)去下胸(xiong)(xiong)(xiong)圍所得到的(de)尺(chi)寸(cun)。國(guo)際通用(yong)的(de)罩(zhao)杯也有制定的(de)標準，因(yin)此我們在(zai)選購(gou)時也可(ke)以(yi)(yi)根(gen)據這個標準，向售貨員表(biao)明自己(ji)的(de)罩(zhao)杯大(da)小(xiao)(xiao)，這樣買到的(de)文胸(xiong)(xiong)(xiong)才不會(hui)偏大(da)或偏小(xiao)(xiao)。

通常選購文(wen)胸也有一定的技巧(qiao)，簡單(dan)來說(shuo)就是(shi)(shi)(shi)(shi)(shi)(shi)分為(wei)看、摸、拉(la)、試四個(ge)步驟。看主(zhu)要就是(shi)(shi)(shi)(shi)(shi)(shi)留意布紋是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)對稱，罩(zhao)杯是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)大(da)小相同以及吊環是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)容易(yi)刮傷皮膚；摸則是(shi)(shi)(shi)(shi)(shi)(shi)弄(nong)(nong)清楚面料(liao)是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)舒適(shi)、是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)吸汗，做工是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)精細(xi)；拉(la)則是(shi)(shi)(shi)(shi)(shi)(shi)弄(nong)(nong)清楚文(wen)胸是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)有彈性(xing)，柔軟性(xing)如何，是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)能隨著身體的運動而(er)作出調整(zheng)(zheng)；試主(zhu)要是(shi)(shi)(shi)(shi)(shi)(shi)找到感(gan)覺，肩帶是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)能合(he)理調整(zheng)(zheng)好，花邊(bian)是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)柔軟，會不會有刺痛感(gan)等。弄(nong)(nong)清楚了(le)這些問(wen)題，挑選文(wen)胸就不會太難了(le)。
