A garment in one aspect of the present disclosure includes an outer fabric and a lining fabric. The outer fabric forms a front body part and a back body part. The front body part includes a first opening to be situated in a center portion of the front body part in a width direction of the garment when the garment is worn over a wearer. The first opening extends in a length direction of the garment. The lining fabric is attached to the outer fabric so as to form an internal space between the lining fabric and the outer fabric. The internal space is formed (i) to accommodate a fan in the internal space and (ii) to let an airflow generated by the fan pass through the internal space.
