The size is US10 EUR40 (I'm assuming it's a Large since there's no SML notation). Approximately 45cm from armpit to armpit when laid flat. About 60cm from the tag area to the hem. Photos 1 and 2 appear slightly brighter, while photo 3 appears darker. It's not pure white. *The inner layer in photo 5 is for reference on transparency only and is not included in the sale. Only the shirt is for sale. This is a used item that has been home-cleaned and stored at home. There are some stains and signs of wear. I will add more photos, so please feel free to comment if you have any concerns. It will be folded small for shipping. Please excuse any creases.
