Navy Striped Button Up Shirt

Navy blue and white button up collared shirt. Can be dressed up or down. Labeled as a small, but fits more like XS in my opinion. Bought with intentions to wear, but it's too tight in the shoulders for my liking (I do not have XS shoulders.) Slightly fitted like first model photo depicts. Comes with an extra button. Sorry about the wrinkles, it was packed in my suitcase, but I decided against wearing it due to fit.
