My kids have 3 shirts each, 3 pairs of shorts/skorts each, then a pair of sports shorts each for summer. They don't have dresses for the girls so they all wear the same shirts. For winter they have 2 pairs of tracky pants, DS has 2 pair of trousers and the girls have 2 winter skirts each. They have 3 jumpers each and 1 sports jacket each. I have found that this is a good quantity to have through winter incase you have a run of wet weather and can't get anything washed and dried. They will wear a jumper for a week though before it needs to be washed unless they get something on it.
