"You are all girls."

Translation: Εσείς είσαστε όλες κορίτσια.

[Thomas.hnn]

Why "all" is not in the translation? I put "ολες" before the word "girl".
Thank you

I guess it would be όλα, but I'm not sure

The answer gives εσείς είσαστε κορίτσια as a translation of " You are all girls" , is the όλες really not necessary to capture the English meaning?
