She's a cute girl.
Literal
She [topic-は] cute girl is.
A bare-bones polite affirmative. Notable mainly for its use of かわいい as an attributive (modifying 女の子) rather than predicative; かわいい is an i-adjective and slots directly before nouns without any linking particle. 女の子 covers both 'girl' (young female) and 'baby girl' depending on context — Japanese leaves age vague when context establishes it.
