Did you have your college dorm on your driver's license? No. A few questions here: first, the undressing-yeesh, right? But also, did the driver go pick up clothes Ana already owns from her house? How would he know where Anastasia lives? She's a college student who's moving out of her presumable student housing after graduation, so it's not like it would be on her driver's license.
And Christian also sends his driver to get more clothes for her since she vomited on her outfit from last night. So Ana goes out to a bar with her friends, gets very drunk, and drunkenly calls Christian who picks her up and brings her back to his hotel to sleep it off (he also changed her into pajamas which feels excessively wrong).
