Experts have lifted the lid on how often women should wash their bras - and the results may surprise many clean freaks.
專家揭曉了女性應該多久洗一次胸罩的答案，結果令清潔狂們大吃一驚。

According to a textile expert, bras that are washed too frequently can become damaged, which causes them to lose elasticity and become less supportive, which can be harmful to the wearer.
一位紡織專家說，胸罩洗得過頻繁容易被損壞，失去彈性，承托性下降，最終對穿戴者不利。

'Over-washing can damage the elasticity, which is essential for providing the proper support,' Lexie Sachs, product analyst in the Textiles Lab at the Good Housekeeping Institute, told Cosmopolitan.
“過度的清洗會損害胸罩的彈性，而彈性是發揮胸罩承托功能的關鍵，”好管家協會（Good Housekeeping Institute）紡織實驗室產品分析員萊克茜·薩克斯（Lexie Sachs）這樣告訴《時尚》雜志（Cosmopolitan）。

Unless you're really sweaty, she suggests waiting three or four wears, approximately ten days depending on the wearer, before washing - but adds that this is also dependent on the activity level of the wearer.
除非你真的出汗很多，否則的話她建議還是穿個三四次，也就是大約十天后再清洗。但是她也補充說，這得根據個人運動量多少而定。

So the sports bra that gets worn every day will need more frequent washes than the special occasion lacy balconette bustier that lives in the back of the drawer.
所以，每天都穿得運動胸罩需要更常清洗，相比之下，那些平常壓箱底，只在特別時刻穿上的蕾絲緊身胸罩就不用洗得太頻繁。

'You should have several bras to rotate through to avoid stressing elastic over time, but wearing the same bra two days in a row isn't an issue,' says Sachs.
“你應該多備些胸罩，替換著穿，以免穿戴時間過長失去彈性；但一件胸罩連續穿一兩天也絕對沒問題。”薩克斯說。

'Taking it off at night should allow plenty of time for it to recover its shape and elasticity. If it can't do that in eight to 12 hours, waiting an extra day won't make a big difference.'
“脫下來一個晚上已經有足夠長的時間讓它恢復彈性。如果一件胸衣在8-12個小時內不能恢復彈性，你再多放一天也沒用。”
