Biting lips: okay, this may be too common, but for someone who might have just crawled out of a rock, when a woman bites or chews her lips when you’re talking to her it means she is flirting. Women do this to draw out your attention to her lips.
Dilated pupils: a dilated pupil usually is an indication of being attracted to the other person. So if you notice her pupils dilate when she looks at you or when you’re together, it usually means that she is attracted to you. This, of course, is applicable to both men and woman.
Flared nostrils: if you’re looking for signs to assume if she likes you or not or if she’s flirting with you, her nostril is probably the last thing that you want to look at. But, on the contrary, her nostrils can also help you determine that. If her nostrils flare up, it’s usually an indication of being attracted to you. It’s an involuntary action that occurs when one feels excited, so it’s a genuine body language of flirting or being attracted.
Fiddling or playfulness is one another prevalent body language that indicates if she is flirting with you. Look if she fiddles with her hair, jewelry or any other irregular body movements to understand if she’s flirting with you.
Fiddling hair: if she fiddles her hair too often when you’re together it usually means she is flirting with you. However, fiddling hair too frequently can also mean that she is bored. The key is to look for a smile when she fiddles her hair. If her fiddling is accompanied by a coy smile, it means she is attracted to you.
Fiddling jewelry: fiddling jewelry or objects are a part of involuntary action. When a woman is interested in you, your presence will make her restless and excited in a nervous way. This automatically results to her body responding in a restless manner such as playing with her earrings, twisting her rings or play with her necklace.
