It might be better to use "worrying" — the process — rather than "worries" — specific concerns.

1. The sentence "The dress fits in you" is grammatically incorrect. The correct phrase is "The dress fits you," which means that the dress is the right size for you.

2. The sentence "The dress fits you" is grammatically correct and means that the dress is the appropriate size for you.

3. The sentence "The dress becomes you" is grammatically correct but conveys a slightly different meaning. It suggests that the dress enhances your appearance or suits you very well.

4. The sentence "The dress looks good on you" is grammatically correct and means that the dress suits you and makes you look attractive.

5. The sentence "The dress is suitable for you" is grammatically correct and means that the dress is appropriate or fitting for you.

All of these sentences are grammatically correct, but they have slightly different meanings.

Regarding the second set of sentences:

6. The sentence "My mother gives advices about worries" is grammatically incorrect. The word "advices" is not used in English to refer to multiple pieces of advice. The correct phrase is "My mother gives advice about worries."

7. The sentence "My mother gives advice about worries" is grammatically correct and means that your mother provides guidance or suggestions regarding worries.

8. The sentence "My mother gives pieces of advice about worries" is grammatically correct and conveys the same meaning as the previous sentence, but with a more specific emphasis on individual advice.

9. The sentence "My mother gives some pieces of advice about worries" is grammatically correct. The addition of "some" indicates that your mother provides a few pieces of advice about worries.

In English, "advice" is an uncountable noun, so it does not have a plural form. We always use "advice" to refer to any number of instances of guidance or suggestions.
