I don't see anything wrong with a child getting dirty in kindergarten. After all, it's just clothes, and a child should remain a child. I love to dress up my kids. And for the cold season, I knit sweaters and coats for them myself, very practical and beautiful. I buy luxury yarns here https://www.badmayarns.com/ The quality of materials is great, the kids are not cold and look very neat. Any washings are just as good.
