She changed into her pajamas when we got to her apartment?

This was our first night out. We've been friends for a year but this is the first time we've gone out together and had an amazing time doing so. We ended up at her apartment and she changed into pajamas. They were kinda revealing, more than I 've seen from her before. Did she want something to happen or just felt comfortable with me?
