Here's a breakdown of the main conflict:
* Wanda Petronski, a Polish girl new to the school, is constantly ridiculed for her plain clothing and her foreign heritage. Her classmates, especially Peggy and Maddie, make fun of her and spread rumors about her. This creates a hostile environment for Wanda, making her feel isolated and ashamed.
* Peggy and Maddie, while initially participating in the bullying, begin to realize the cruelty of their actions and the negative impact they have on Wanda. They struggle with guilt and the desire to make amends, yet fear the consequences of standing up against their peers.
* The story explores the internal conflict within Peggy and Maddie as they grapple with their own prejudices and the desire to be accepted by the popular crowd. They have to choose between their own comfort and the well-being of someone different from them.
* The conflict highlights the power of words and the lasting impact of prejudice. It also explores themes of self-worth, empathy, and the importance of standing up for what is right.
The conflict culminates in Wanda's departure and her imagined collection of one hundred dresses, symbolizing her resilience and her ability to find beauty and value even amidst prejudice.
