A woman's awkward or shy behavior around you specifically, not as a general trait, signals attraction. The key is whether her discomfort happens only when you're there. Consistent, targeted awkwardness is a strong indicator she finds you appealing.
When you're reading somebody's body language, you do wanna make sure you keep things in context. One of the ways to do that is, are you the exception? If she just acts awkward with everyone, it's not necessarily a sign. But if she acts awkward every time you walk in the door or she has to talk to you, that's a very, very good sign that it's like, "Oh, I have some impact on her and how she reacts." That's a good sign that, yeah, it's 'cause she's like, "Oh, shoot, he's so cute."
