Sense of humor. A girl who doesn't take themselves too seriously. And someone who is spontaneous. They're the three things for me that really attract me to a girl.

Sense of humor means someone has the ability to be funny and make jokes. A girl who does not take themselves too seriously means that she is able to enjoy life, relax and not be overly serious in all situations. Someone who is spontaneous refers to someone who is willing to take risks and be unpredictable – they can surprise and make things more exciting. All of these things are what make someone attractive to the speaker in this quote.
