What's the Name of That Book??? discussion

I need help finding the title of a children's picture book I remember from when I was little. Here is what I remember about it (keeping in mind my mom read this book to me when I was probably 4 or 5 years old, so some of the details are a little fuzzy...):

1. It is a picture book, no chapters, aimed at preschool or kindergarten aged children.

2. It was probably published in the 1970s or 1980s. I'm basing this on what I can remember of the illustrating style and the fact that my mom read it to me, so it was written before I could read myself. It's possible that it was written earlier than that, but I don't think so. The 80s are the most likely decade.

3. The main character is a little girl (probably 4-6 years old) with an extremely active imagination that gets her into trouble. I think she had a black leotard, and her hair was messy. I also think that her tights were bunched up instead of nice and smooth. No matter how hard she tried to behave, her rather active imagination always seemed to get her into trouble.

4. I believe that most or all of the story takes place in a dance class. At one point, the teacher tells the children to pretend they are trees blowing gently in the wind. The main character's imagination gets a bit carried away, and gently blowing in the wind turns into a wild windstorm. I think she knocks some other children down. The other part I remember is that the teacher asks the children to pretend they are animals. The other girls are graceful animals, but the main character pretends she is something ferocious (maybe a lion or tiger?) and ends up biting another little girl on the leg (I think.) I can't remember anything else that happens, but I'm pretty sure the other incidents were along those lines.

5. I think the illustrations were drawn without a lot of color, but this memory is probably 30 years old, so I could be wrong about that. The illustrations in Eloise have always reminded me of this book, but I am almost certain it isn't from an Eloise book because I don't think I read those as a child, and none of the descriptions fit what I remember. The illustrating style in the Christina Katerina books also look like what I remember. I've checked all those, though, and none of them (even the ballet one) seem to fit the bill, based on the synopses I've read. I am certain that at least some of the illustrations featured several girls at a barre, doing exactly what the teacher said, and the main character doing something completely wrong (maybe hanging upside down from the barre at one point?) Maurice Sendak's illustrating style also comes to mind, as well as the illustrations in Judith Viorst's books about Alexander. I know that those books all have completely different illustrations, but the basic style of them reminds me of what I remember.

6. Books I am certain it is not that have been suggested: Ramona Quimby (or anything by Beverly Cleary), Madeline, anything with animals as the main characters, Fancy Nancy, Ivy and Bean, anything by Noel Streatfield, The Silver Slippers

Thanks!

Myra by Barbara Bottner maybe?

Oh my goodness! I think that might be it!! Thank you!
