What if a girl apologizes for her appearance?

So, this girl that I (a girl) hungout with recently and I had been texting for awhile. We decided to meet up. She was very diff. in person (usually curt over texts), and seemed excited to see me/talkative. After we were talking for a bit, she apologized for her work clothes (she sort of dresses like that normally though from what I recall, so I felt it was out of the blue). She then mentioned that her would've been able to stay longer, but that her plans had gotten messed up. She also joked about how she hadn't had time to go and change/shower or plan if she was going to wear make up (I was wearing some, but hadn't seen her in any before). Does this indicate friendliness or was she hinting towards flirting/liking me?
