When I started my budget a few months ago, I budgeted $70/month for clothing. This is for me, DH and our 3 boys. It includes outerwear, accessories and shoes.
We don't really have any good thrift stores in our area, but if I happen to see something good at a garage sale, I'll buy it. I am good about handing down clothing from boy to boy, so we rarely have to buy outerwear, snow boots, etc.
Other than that, we buy our stuff new, but we try to find good sales, limit what we buy, etc. All of us have minimal wardrobes. It would be difficult for us to go a week without doing a load of laundry.
Still, we are going over our budgeted amount every month! I guess I'll have to put more money into the clothing budget, but I'm just curious what other families spend. It seems that a huge part of our cost is shoes. We don't buy anything fancy, but good shoes/sandals for each family member cost A LOT!
