* Smoothness of skin: Recently shaved skin might feel smoother than unshaved skin.
* Lack of visible hair: The absence of hair in areas where people commonly shave (legs, underarms, etc.) *could* indicate shaving, but could also mean other hair removal methods are used or that the person naturally has little hair.
* Razor bumps or redness: These can sometimes appear after shaving, especially if the technique wasn't perfect.
Ultimately, the best way to know if someone shaves is if they choose to tell you.
Important considerations:
* It's her choice: Whether or not a woman shaves is entirely her decision.
* It's not your business: It's generally considered impolite and intrusive to speculate or ask about someone's grooming habits.
* Respect her privacy: Don't try to find out without her consent.
Instead of focusing on whether or not someone shaves, it's much better to focus on being respectful and treating them as an individual.
