Childrens book with a girl with pink overalls

It was a series of books, the MC had black hair, square glasses, pink overalls, a stripped shirt underneath, and she visted her grandma often, or she lived with her I can't remember. I think its more popular in the UK than other countries, not sure tho since ive never really searched

I read this book in 2021/2022, im not sure the year it was made, im assuming somewhere around 2017/2018
