I was doing this until very recently. I got fed up with ds #2 refusing to wear anything but the same pair of shoes so now he has a pair of sandals & a pair of athletic shoes. If one gets wet or dirty, he has the other type. I was buying him two pairs of each for a back-up & finally lost my mind when he had a favorite pair of each & refused to ever wear the others.
A waste of money, although a boon for my two friends I pass their stuff on to.
I have friends with girls who have all this stuff they wear. Here? Not so much. LOL! Even ds #1, who for a long period was interested in looking nice, has changed his ways. So far, I can still get away with insisting - and I have to insist - that their shirts & shorts don't totally clash but that's the level we're currently at.
