"ere we may think her ripe to be a bride" (Capulet)
1) The fact that we meet Juliet through male conversation before herself, emphasises her place as a wealthy teenage girl in a patriarchal society - she has her life mapped out for her by her father.
2) 'ripe' has connotations of fruit - she has no control over her fate.
3) 'ripe' also would mean she is in her prime and if left too long would go off like fruit. This reflects the fate of unmarried women in Elizabethan patriarchal society - married off young.
