Kindergarten Teacher Clothes??

I’m starting a job next week as a kindergarten teacher and there is no uniform. I’ve never had a casual uniform job before and I need some recommendations on what clothes to buy/wear. The Kinder seems to have a pretty relaxed uniform code which helps. I’m 4”11 size 6-8 for reference.

Edit: thanks everyone for the recommendations!! Now I have to prepare my bank account haha
