1) I can’t be masig spending much more than 20 dollars on any shirt.
2) Where are they copying it from? Is it that they see the ties in the store? Did they see bachurim from an even more up to the minute yeshiva wearing them? Someone has to be first and it doesn’t necessarily mean anything. It could be that they saw the tie and liked it. Or a relative bought it for them….
3)How expensive are the sneakers? Maybe they were dirt cheap. If not, a lot depends on whether the boy’s feet stopped growing. I guess I would say the same thing I’d say to my daughter: I’m willing to spend up to $ XX and you can pay the difference. If the difference were exhorbitant, I’d try to get to the root of it all, and build up my son’s self-image that he wouldn’t feel the need to blow significant amounts of bar mitzvah money on such externals.
