This is a 100% cotton shirt from Tomorrowland MACPHEE. It does not contain any stretch. It has a unique design with hidden buttons. There is no size indicated on the product, so I've listed it as a size M, but the actual measurements are: Width: Approximately 44cm Shoulder width: Approximately 37.5cm Length (from collar to hem): Approximately 62cm Please use the above as a reference. I have home-laundered and stored it at home. I haven't ironed it, so there are wrinkles, but I will sell it as is. Please understand. I think it's in good condition, but there may be oversights. I appreciate your understanding if you are purchasing a used item.
