Don't Judge Me joins other books for young readers that address the issue of school dress codes and their treatment of girls' bodies. I appreciated the way it was shown that the dress code itself wasn't the sole problem, but rather more generally the school's culture of sexist bullying, and I liked how Hazel's parents, especially her mom, supported her and inspired her to speak up. The writing was mostly smooth, though the dialogue didn't feel very natural, and there's a rushed time-skip at the end where information that was previously withheld from the reader is revealed, which I found kind of annoying.
There's some diversity in the secondary characters--there's one mention of Hazel's friend Tori being dyslexic, and Tori has two moms. Their new friend Dion is implied to be Black. It mostly felt pretty surface-level, though. I wish these books about dress codes would handle the topic in a more intersectional way--like, talk about how these issues can disproportionately affect students of color, or those who have disabilities, or are gender-nonconforming, or come from low-income families.
I didn't like how Tori really peer-pressured Hazel into performing in the school talent show--that was never challenged. There's also a weird Netflix-and-chill joke that felt out of place in a middle-grade book.
As others have pointed out, the cover design leaves something to be desired--it's made clear how Hazel has been bullyed for being on the heavier side, but none of the girls on the cover reflect this.
