文胸是女人的第二層肌膚，其功能主(zhu)要是為了幫(bang)助女性乳房提(ti)供外部支(zhi)撐，避免造成(cheng)疼痛不(bu)適(shi)，這就意味著文(wen)胸(xiong)(xiong)必(bi)須(xu)有足夠的(de)(de)舒適(shi)性以(yi)及(ji)支撐力。因(yin)此，女性在(zai)(zai)選購(gou)適(shi)合自己(ji)的(de)(de)文(wen)胸(xiong)(xiong)之前(qian)，還需要學會(hui)如何量罩(zhao)杯，以(yi)及(ji)分清(qing)楚胸(xiong)(xiong)罩(zhao)尺(chi)(chi)寸(cun)和罩(zhao)杯尺(chi)(chi)寸(cun)的(de)(de)區(qu)別。胸(xiong)(xiong)圍通常是指(zhi)沿女性乳頭繞胸(xiong)(xiong)一周的(de)(de)長度，而(er)胸(xiong)(xiong)罩(zhao)尺(chi)(chi)寸(cun)指(zhi)的(de)(de)是下胸(xiong)(xiong)圍繞一周的(de)(de)尺(chi)(chi)寸(cun)，罩(zhao)杯尺(chi)(chi)寸(cun)即胸(xiong)(xiong)圍減去(qu)下胸(xiong)(xiong)圍所得到的(de)(de)尺(chi)(chi)寸(cun)。國際通用的(de)(de)罩(zhao)杯也有制定的(de)(de)標(biao)準(zhun)，因(yin)此我(wo)們(men)在(zai)(zai)選購(gou)時也可以(yi)根(gen)據這個標(biao)準(zhun)，向售(shou)貨員表明(ming)自己(ji)的(de)(de)罩(zhao)杯大小(xiao)(xiao)，這樣買到的(de)(de)文(wen)胸(xiong)(xiong)才不(bu)會(hui)偏(pian)大或偏(pian)小(xiao)(xiao)。

通(tong)常選購文(wen)胸(xiong)(xiong)也(ye)有一定的技巧，簡單(dan)來說就是(shi)(shi)(shi)分(fen)為看(kan)(kan)、摸、拉、試四個步驟。看(kan)(kan)主(zhu)要就是(shi)(shi)(shi)留意(yi)布紋(wen)是(shi)(shi)(shi)否(fou)(fou)對稱，罩杯是(shi)(shi)(shi)否(fou)(fou)大(da)小相同以及吊環(huan)是(shi)(shi)(shi)否(fou)(fou)容易刮(gua)傷皮(pi)膚；摸則是(shi)(shi)(shi)弄(nong)清(qing)(qing)楚面料(liao)是(shi)(shi)(shi)否(fou)(fou)舒適、是(shi)(shi)(shi)否(fou)(fou)吸汗(han)，做(zuo)工是(shi)(shi)(shi)否(fou)(fou)精細；拉則是(shi)(shi)(shi)弄(nong)清(qing)(qing)楚文(wen)胸(xiong)(xiong)是(shi)(shi)(shi)否(fou)(fou)有彈性(xing)，柔軟(ruan)性(xing)如何，是(shi)(shi)(shi)否(fou)(fou)能(neng)隨著(zhu)身(shen)體的運動而(er)作(zuo)出調整；試主(zhu)要是(shi)(shi)(shi)找到感覺，肩(jian)帶是(shi)(shi)(shi)否(fou)(fou)能(neng)合理(li)調整好，花(hua)邊是(shi)(shi)(shi)否(fou)(fou)柔軟(ruan)，會不會有刺痛感等。弄(nong)清(qing)(qing)楚了這(zhe)些問題，挑(tiao)選文(wen)胸(xiong)(xiong)就不會太難了。
