name doesn't fit

Could you correct the paragraph?
Is it correct to say that a name doesn't fit a person?
Is it correct and common to say that a name is harsh or sweet?

I know that nothing is set in stone, if she is born and her name doesn’t fit/the name doesn't fit her, we can always change our mind. I can't wait to see if her name fits her once she's here. Some names are harsh sounding, others are sweet sounding. I want to name her xxx which I think is harsh sounding but if she arrives and I feel the name doesn't fit her because she looks very delicate and sweet, we'll have to give her a different name.

Thank you very much
