Abstract: A rivet device for securing compressible media is provided herein. The device comprises a rivet with head and shaft portions and a receiving unit. The rivet and the receiving unit are adapted for cooperative reversible rotational engagement. The rivet shaft is inserted into and passes through an aperture in one or more media and engages with the receiving unit on a surface of the media opposite the rivet head portion. Relative rotation in either direction between the rivet and the receiving unit directs reversible engagement of the rivet device. When the rivet device is engaged, the rivet head portion and the receiving unit cooperatively resist tension from the secured media. The rivet shaft is constructed to prevent buckling under pressure or bending under shear from the secured media. A costume assembly kit employing the rivet device to fasten substantially planar costume panels to produce a three-dimensional costume is also provided.
