I would not use that comma. But I would put one after "remove".
Student or Learner
. . . And the young woman came into my store(,) wearing a hat, which I told her to remove so I could see her hair and offer her a fair price for it.
I tried to write such a sentence. I would like to ask if the coma before 'wearing' is necessary or not?
You would not because that comma changes the meaning of the sentence, isn't it?
I just wanted to learn why it is incorrect.
Not it would not. However, I think the sentence ''He swam to the side, using the breast stroke'' needs a comma before 'using' and I wonder that what the difference between the original sentence and this one.
I am asking because I really feel confused about it.
You're going to buy her hair?
