If it was up to my son, he would wear his Nike shorts and t-shirts every day. I admit, I'm partially at fault for this because he has about 6 pairs of those shorts and tons of t-shirts. But they are used mostly for sports.
When I ask him to change into something else, he grumbles for a while but will do it anyway. Sometimes, I just want him to look like he DIDN"T just come from football practice.
When your kids are being stubborn about what they want to wear, do you usually have final say or just let them be?
