8. Don't buy anything that you don't know you need--this is especially important with clothes. 不要买自己都不知道是否需要的东西,尤其是衣服。
If you're not careful, you can buy a pair of pants marked down 75%, then realize that you can't really wear them unless you buy the right shoes to go with them。
如果你不小心,你可能会买下一条标价2.5折的裤子,随后发现只有再买一双鞋和它搭配,否则根本穿不了。
