We must hate hate and destroy evil. Turning the other cheek is irresponsible. This is why bad seeming things like going to war can sometimes be good. You want to be sure you are right, though. It is immoral to wear expensive clothes.
Fashion is an arms race.
The harder you try, the harder those around you must try. Dressing nice makes the poor and unattractive look and feel worse than they would if you dressed down. The more you get the less there is for others, unlike in business, where one persons success helps to fuel success for the whole society. Any smart person can see that it is dumb and wasteful to through away a shirt because of a spot. Every wasted dollar adds to the toil and often to pollution.
