Perhaps I'm just not getting this?

Question

Above, you say:
C'est  in sentences "it is + a/the/my... + thing"

C'est une jolie robe.
It is a pretty dress.

The sentence above is referring to a specific dress, otherwise how could we say it is pretty?

Yet, further down the page, I read this:

"...Il est/elle est  for statements and opinions related to specific things:

Tu aimes mon pull ? -Oui, il est très beau.
Do you like my sweater? -Yes, it's very nice..."

According the this, the sentence should be: "Elle est une jolie robe".

Accepted Answer

Yes, we'll work on this lesson very soon, but in the meantime, the difference in these specific cases is that c'est is followed by a noun, while il / elle est is followed by an adjective.

Answer

Thanks Laura!

Answer

Is this correct: 
Tu aimes mon pull ? -Oui, il est très beau.
Or
Tu aimes mon pull ? -Oui, c'est un très beau pull.

Answer

Why is this not a broad general statement that uses C' ?  Please explain exactly why C' is incorrect. I have grown vert frustrated trying to understand this.

Answer

Pauline, the answer is : elle est jolie.

Answer

Could you give a synopsis, I mean a short clue to get this c'est and Il/elle?

From your previous reply, you texted, c'est is followed after a noun and il/elle is followed after an adjective. Could you please site an example?
