If you’re looking for translations;

1: She is the most beautiful woman in the city.

2: She is one of the most beautiful woman in the city.

If you’re looking for the correct saying, I think it’s numero dos (#2).

Ella es una de mujer más bella de la ciudad.
She is the most beautiful woman in the city.
She is one of the most beautiful woman in the city.
She is one of the most beautiful woman in the city.
