I am not sure if I am attracted to her, after seeing her without make up, should I still give it a chance?

I met a girl during a new years party. She looked so beautiful I couldn't keep my eyes of her. We were talking and dancing all night. After the party we started texting and she is also cool, intelligent , funny and very good person. I met her again, among friends (we went on a trip). And without make up and in daylight, she wasn't so gorgeous anymore. I wanted to invite her on a date, just us two, but I am not sure if I am still attracted to her. I am very handsome and hot girls sometimes throw themselves at me. But it's rare to meet someone so intelligent and nice, and I am already 33. But I have to be 100% sure to be attracted to them?
