SOLVED. Children's Picture book. Classmates copy the main character. Read in 1990s. [s]

I'm looking for a children's picture book where the main character (a girl) would do something and her classmates would have copied her the next day. I remember there being a daisy sweater ( I think she painted them and pinned them to her sweater, she wore her hair in a pony tail unicorn style, and finally she was so exhausted of them copying her, so she threatened to shave her hair off, and the next day everyone had shaved heads. I'm not sure when this book was published but it seemed like a contemporary book back when I read it as a kid in the early to mid 90s. Thanks!
