衣櫥里衣服成堆，可還是覺得沒有衣服穿？不如找一天來一場“衣櫥血拼”吧。你不用花一分錢，只需把衣服全部整理一遍，就有可能會發現好幾件很不錯的“新”衣服。

Closet shopping is a kind of shopping you don't have to spend a penny, you just need to look through your closet and discover articles of clothing you forgot you bought or owned, you haven't worn in a while, or you have been saving for when you can finally fit into them again.
“衣櫥血拼”是一種無需花錢的購物方式，你只需打開你的衣櫥，把里面的衣服都整理一遍，然后會發現一些你忘記自己買過、很久沒穿，或者買了等瘦下來再穿的衣服。

Closet shopping can also refer to the act of going through all the clothing you own and putting together new outfit combinations that you never thought of before.
“衣櫥血拼”還可以指把衣櫥里的衣服重新整理一遍，然后找到了一些原來沒想到的搭配方式。

For example:

I have been doing closet shopping this past weekend, and I found TEN new shirts that I have never worn before. What was I thinking!
上周末我一直在“衣櫥血拼”，找到了十件從來沒穿過的襯衫。也不知道我當時怎么想的。
