Material: Cotton 100% The size isn't indicated, but it looks like a size M. The fabric is thin like gauze, and the sleeves have frills, making it very cute. Layering it and showing the frills from the cuffs is also a great way to wear it! ^_^ *Please note that this is a new, unused item, but it has been stored and inspected by a private individual. It will be shipped folded up small. #Women'sShirt #Checkered
