Even a kid can understand that some dress is appropriate or fitting for the hour and some is not.
As kids when when my brother and I dressed well our dad would sometimes say: "You boys look sharp." This meant a lot and taught us well.
In this image one guy looks sharp and the other does not. If you are in a position of trust and leadership such as the priesthood then dress for the hour and accept no substitutions and you will be respected for it.
