Question:
How much mascara is halachadig allowed?
Answer:
It is hard to give an exact measurement, however I once heard from guideline from a very famous chosson teacher, that “she can put on an amount that will make her beautiful, but not an amount that will make her look like mascara”. Meaning, that if the mascara (and makeup) is accentuated too much, someone looking at her is not noticing her, but her mascara and makeup.
