This is a Hiroko Bis dress. There is a brown dress underneath a sheer T-shirt. This is a set. As shown in the last photo, there is an original sewing error on the back of the brown dress worn underneath. It should be fine if you wear them together, but you may be concerned if you wear only the dress underneath. Please understand that the following measurements are taken by an amateur. T-shirt Shoulder width: 41 cm Sleeve length: 22 cm Body width: 65 cm Length: 50 cm Dress Sleeve length: 17 cm Shoulder width: 40 cm Body width: 43 cm Total length: about 150 cm
