if she has the money, i dont see why she wouldnt/shouldnt spend it on nicer and more expensive things for herself...if you were the #1 artist of a major record company making tons of money, would you be walking around wearing 3 for $10 chinatown t-shirts? hmm.... about money not being spent on starving african children, it is NOT ayu's responsibility to end world hunger or save as many lives as she can. ayu's responsibility is ayu herself! as much as we all love ayu, shes human too. its only human nature to take care of yourself before others. she should be able to enjoy HER OWN LIFE from her success. i personally dont see anything wrong with her spending her hard earned money on things that she likes. in my opinion, LV looks great on AYU!
of course, opinions are like bellybuttons... everyone has their own (and are entitled to it).
