DD starts YR this September. She's spent most of her life at childminder/nursery/preschool and does a good amount of crafts/art/outdoor playing. Yet it's rare she's needed a change of clothing. She's a bit of a neat-freak and rarely comes home dirty. As a family we do three clothes washes a week. With this in mind, how many school dresses/skirts/polo shirts/sweatshirts do you think I'd need to buy for her?
