This is a THEORY petit white short-sleeved shirt (with a collar). Please check the size details below. Since there was no THEORY option for children's clothing, I have selected the women's category for listing. Brand: THEORY petit Size: 150 This can be worn by petite women. I have actually worn it myself, even though I am an adult. There are no noticeable stains, but there are fold creases as it has been stored folded. Thank you for your understanding.
