Dilated pupils are a sign she's attracted to you, but you have to look directly at her eyes to notice. Prolonged eye contact can increase mutual attraction, though staring will backfire.
The next body language sign that a girl likes you is that her pupils dilate. This is remarkably common when someone is attracted to someone else, is that their pupils will dilate. Another fun thing about looking for this sign is, you know, you obviously have to look into her eyes in order to see if this sign is happening, seeing if they're dilating. And fun fact for you, looking into someone's eyes for prolonged periods of time actually can dramatically increase attraction. So it's kind of a nice sign to be looking for. Obviously, don't stare her down. That will have the opposite results of what you want. But paying attention to see if her pupils dilate is definitely a fun one.
