I think you should wear jeans because they are comfortable and wearing blue will make you feel calm.

问题描述:

I think you should wear jeans because they are comfortable and wearing blue will make you feel calm.
在这里为什么用wearing 而不用wear?

wearing blue will make you feel calm 可以看作一个从句
wearing blue 在这里作为名词词组 做 will make的主语 wearing在这里是动名词
