It's a good idea to let them start school and see what their friends are wearing. When it's so warm the beginning of the school year you can get away with summer clothes for a while. I hate to see kids caught up the name brand thing but it's more important to some than others-and if a new shirt gives them a confidence boost that's ok. It's also ok to let them know this is how much we can spend-how do you want to make it work?
