Do you think a girl that flashed her boobs at you is girlfriend material?

I am actually attracted to her and consider her a friend (we work together) and thought she is girlfriend material. She always acts respectful and classy but the other day, when we were at a job, she was calling my name and when I turned to look her way, she flashed her boobs. I kind of lost some of my feelings for her tbh... I was just surprised by that behavior. Not that I'm a prude but there's other ways she can show if she's interested. It also makes me wonder if she's just an "easy" girl. I'm I wrong for thinking this way?
