If you scroll down the Q&A section at the bottom of this lesson , you will see that there is quite a lot of discourse regarding when to use, c'est and il/elle est-
You cannot say in French - 'Elle est une bonne nageuse' but, 'C'est une bonne nageuse' is the only correct sentence.
It is the same for "It is a pretty dress" you cannot use Elle here -
"C'est une jolie robe " is the only acceptable answer.
Hope this helps!
You can also say :
Elle est bonne nageuse ( no 'une' which is never possible after - elle est ....
This is why we say :
Elle est prof d'anglais
Il est architecte
elles sont médecins
