This is a brand new t-shirt that never has been worn. No tags. This t-short was bought by mom my in Europe for me however it is too tight in arms. I am usually small. So even though it says on t-short medium , it really is small/XS . I have a bit bigger arms and shoulders so usually small can be tight on me in that area. I don’t think this is an authentic, however, material is really good. And looks great. Let me know if you have any questions.
