This is a tough, as it depends on what they like to wear.

DD1 has 3 summer dresses, that she chooses to wear all year, she just changes the type of tights she wears. There is no proper winter uniform, other than trackies and a polo shirt, both of which she has refused to wear. She also refuses to wear skorts, even though I bought 3 them, plus tops. Also have the polar fleece jacket and vest, along with a couple of basic windcheaters.

I am spending a fortune on tights Just wish that girl would wear socks.
