Clothing comprising: a clothing part configured to surround a human body to protect the human body; and an accommodation part connected to the clothing part and configured to provide an accommodation space which is a predetermined space in which a predetermined object is receivable, wherein the accommodation part forms one surface together with the clothing part as an accommodation coupling part which is a part of the accommodation part is coupled to a clothing coupling part which is a part of the clothing part in a storing position, and provides the accommodation space which is a space in which a predetermined object is receivable, together with the clothing part as the accommodation coupling part and the clothing coupling part are separated from each other and thus a portion of the clothing part and a portion of the accommodation part are spaced apart from each other in an accommodation position, wherein the clothing part includes a left arm part providing a predetermined space into which a left arm of a wearer is insertable, a right arm part providing a predetermined space into which a right arm of the wearer is insertable, and a backplate part connected to the left arm part and the right arm part and configured to surround a back of a human; characterized in that the backplate part includes a first backplate part providing a predetermined area, a second backplate part providing a predetermined area, a third backplate part disposed between the first backplate part and the second backplate part to be connected to the first backplate part and the second backplate part, and the clothing coupling part connected to a portion to which the first backplate part and the third backplate part are connected and a portion to which the second backplate part and the third backplate part are connected; the accommodation part includes a base part, one side surface portion connected to one side of the base part and one side of the third backplate part, the other side surface portion connected to the other side of the base part and the other side of the third backplate part, and the accommodation coupling part connected to the one side and the other side of the base part; and the base part is disposed so that one end portion of the base part is fixed to the third backplate part and the other end portion of the base part is spaced apart from the third backplate part so that a separation distance between the base part and the third backplate part gradually increases from the one end portion of the base part toward the other end portion of the base part when the accommodation part is in the accommodation position. a clothing part configured to surround a human body to protect the human body;
