Is it okay to date a woman older than me?

Problem/Goal: Is it okay to date a woman older than me?

Context: Hi. I am 18 years old, and I like someone who is 25 years old. At first, I thought she is only 22 or 23 because she really looks young. Now, we're currently talking, and I just would like to seek an advice if it is okay to date a woman that is 7 years older than me? I really like her, and we definitely clicked, but I want to know if it would be frowned upon if I date her?

Previous Attempts: None.
