[Problem] To provide a body protection product such as a wetsuit that does not require a troublesome and time-consuming step such as machine sewing, does not cause discomfort for the wearer, and does not result in a loss to the degree of freedom in terms of design. [Solution] A wetsuit (10), in which a highly stretchable and elastic sheet-shaped fabric is draped so as to match the concave and convex features of the body shape of a wearer and a plurality of fabric pieces (11) are prepared, an adhesive (3) is applied to the draping surfaces of the fabric pieces (11), and the draping surfaces are then pressed against each other and joined without stitching, whereby a three-dimensional clothing base (1) is formed. Next, an adhesive (4) is applied to the surface of the clothing base and stretching is performed, whereby the surface of the clothing base is covered by a stretchable covering material (2) formed to match the shape of the clothing base (1). The clothing base (1) and the covering material (2) are compressed under heating and thereby made to adhere to each other.
