even if u are very rich, its not wise to give her such expensive
gift. what does it show? u are rich, and she's not.. cos she's just
a poor mos waitress and u are rich who can buy LV bag for
her.
if u really want to show ur sincerity and propose to her, make a
card or do something that shows how much u like her. save the
expensive gifts when both of u are really together. u'll have more
than enough occasions to shower her with some lavish gifts.
