Originally, this was a set with a long-sleeved white long-sleeved T-shirt, but this listing is only for the floral tunic. It fastens with two snap buttons at the back. Since it's see-through, an inner layer is essential, but you can pair it with various items like a long-sleeved T-shirt, short-sleeved T-shirt, or camisole, making it suitable for all seasons! Please only purchase if you understand that this is a used item.
