When we meet people for the first time，we often make decisions about them based entirely on how they look. And, of course it's something that works both ways, for we too are being judged on our appearance. When we look good, we feel good, which in turn leads to a more confident and self-assured manner. People then pick up on this confidence and respond positively towards us. Undoubtedly，what's insideis important，but sometimes we can send out the wrong signals simply by wearing inappropriate clothing or not spending enough time thinking about how others see us.

本段段首词so起到了承上启下的作用。前面几段中作者提到了如何挑选衣服，如何确定自己的品位，如何谨慎地去尝试。本段段首作者指出：现在你已经挑选了从个性、外形、颜色上来说都很适合你的衣服, 在此考生需要注意的是之后提出的问题"But does it fit?(它适合你吗?）”。接着作者指出：事实上，如果一件衣服不是完全合适的话, 就不应该购买。然后再看文章的最后一段，作者开始泛泛谈个人形象以及再评价它的重要性，已经不再具体谈如何着装，由此可以推知，本段内容应该是关于如何着装、如何购买服装的最后建议，因此可确定D选项为最佳答案。
