Simply inquire as to her height. A joke about how you want to acquire a little sports vehicle but are scared about driving tall beauties like her around in it. If she's tall, she'll be pleased because you just complimented her. If not, then you better work on finding something else to say. Asking about someone's height is usually a funny question to ask. The answer will depend on many factors such as their age, gender, and cultural background so you should never ask this question if you don't want to know the anwser. However, height can be a good indicator of other traits such as body type and health so if you're looking to get to know someone better then this question is worth asking. Of course, you should also allow them to tell you about themselves! In conclusion, you can ask people about their height but only if you're willing to hear the answer. And even if they tell you, it may not be the truth so use your own judgment when interacting with others.
