Question

Is this sentence grammatically correct?
Every suit of his is expensive. = All his suits are expensive.

I think we should use 'him' instead of 'his.'

Thank you for your cooperation.

Answer

Both sentences are grammatically correct. However, the first one seems a bit unnatural - I might say "Every one of his suits is expensive" or "Each one of his suits is expensive"  instead. The second version (All his suits are expensive) is more likely to be used. In addition, I would say "All of his suits are expensive," as that sounds more natural.

Answer

Hi. The original sentence is correct, you use "his".
