想请教你，最后的on it，这个it是指clothing吗，如果是，应该可以省略这个it？

Question

Guidelines of what not to wear include the same things you wouldn't wear to work. Don't wear shorts, workout clothes, jeans, T-shirts, baseball hats, flip flops, anything suggestive or clothing with questionable comments on it.

Answer 1

with questionable comments on it.是with的复合结构作定语修饰clothing。其中it指的是clothing。on it是介词短语作with宾语的宾补，一般不能省。如果省略it则变成副词on作介宾的宾补，意思略有不同。总之用on it比去掉宾补或用on作宾补具体。来自：求助得到的回答
