文胸是女人的第二層(ceng)肌膚，其(qi)功(gong)能(neng)主要是為了幫(bang)助女性乳房(fang)提供外部支撐(cheng)，避免造(zao)成疼痛不適，這就意味著文胸(xiong)(xiong)必須有足夠的(de)舒適性(xing)以及支(zhi)撐力。因(yin)此，女性(xing)在(zai)選(xuan)購適合自(zi)己的(de)文胸(xiong)(xiong)之前，還需要學會如(ru)何(he)量(liang)罩(zhao)(zhao)杯(bei)，以及分清楚胸(xiong)(xiong)罩(zhao)(zhao)尺(chi)(chi)寸(cun)和罩(zhao)(zhao)杯(bei)尺(chi)(chi)寸(cun)的(de)區別。胸(xiong)(xiong)圍通常是(shi)指沿女性(xing)乳頭(tou)繞(rao)胸(xiong)(xiong)一(yi)周的(de)長度，而胸(xiong)(xiong)罩(zhao)(zhao)尺(chi)(chi)寸(cun)指的(de)是(shi)下(xia)胸(xiong)(xiong)圍繞(rao)一(yi)周的(de)尺(chi)(chi)寸(cun)，罩(zhao)(zhao)杯(bei)尺(chi)(chi)寸(cun)即胸(xiong)(xiong)圍減去下(xia)胸(xiong)(xiong)圍所(suo)得到的(de)尺(chi)(chi)寸(cun)。國際通用的(de)罩(zhao)(zhao)杯(bei)也有制定的(de)標準(zhun)，因(yin)此我(wo)們在(zai)選(xuan)購時(shi)也可以根據這個標準(zhun)，向售(shou)貨員表(biao)明自(zi)己的(de)罩(zhao)(zhao)杯(bei)大(da)小，這樣買到的(de)文胸(xiong)(xiong)才(cai)不會偏(pian)大(da)或偏(pian)小。

通常(chang)選購文(wen)(wen)胸(xiong)也有一(yi)定的技巧，簡單來說就(jiu)是(shi)(shi)(shi)(shi)分(fen)為看(kan)、摸、拉、試(shi)四個步驟。看(kan)主(zhu)要就(jiu)是(shi)(shi)(shi)(shi)留意布紋是(shi)(shi)(shi)(shi)否(fou)對稱，罩(zhao)杯是(shi)(shi)(shi)(shi)否(fou)大小相同(tong)以(yi)及吊(diao)環是(shi)(shi)(shi)(shi)否(fou)容易刮(gua)傷皮膚(fu)；摸則是(shi)(shi)(shi)(shi)弄(nong)清楚(chu)面料是(shi)(shi)(shi)(shi)否(fou)舒適、是(shi)(shi)(shi)(shi)否(fou)吸(xi)汗，做(zuo)工是(shi)(shi)(shi)(shi)否(fou)精細；拉則是(shi)(shi)(shi)(shi)弄(nong)清楚(chu)文(wen)(wen)胸(xiong)是(shi)(shi)(shi)(shi)否(fou)有彈性(xing)，柔軟性(xing)如(ru)何(he)，是(shi)(shi)(shi)(shi)否(fou)能(neng)隨著身(shen)體(ti)的運動而作出(chu)調整；試(shi)主(zhu)要是(shi)(shi)(shi)(shi)找到感(gan)覺，肩帶是(shi)(shi)(shi)(shi)否(fou)能(neng)合理調整好，花邊是(shi)(shi)(shi)(shi)否(fou)柔軟，會不會有刺痛感(gan)等。弄(nong)清楚(chu)了(le)這些(xie)問題，挑(tiao)選文(wen)(wen)胸(xiong)就(jiu)不會太難了(le)。
