COMOLI cotton jersey short-sleeved T-shirt, product number B01-05010, black, size 2. The tag has been removed once, and it has only been tried on, but it has been stored at home, so please refrain from purchasing if you are concerned about the condition. The following is a quote from the website: This short-sleeved T-shirt uses the standard cotton jersey fabric, with a moderate crispness and a slightly relaxed silhouette. It can be worn on its own or as an inner layer, and the excellent balance is unique to this brand. It may not be surprising, and I think it's an item for everyday wear, but having this cut-and-sew as a base will make your overall coordination better. You'll find yourself wearing it every day, and you'll end up needing to buy more – it's a bewitching piece.
