It might be possible to complain about this product and it might be possible to laugh. The buttocks bra with a registered trademark symbol.
I picked up a brochure about this product today in a department store. The brochure doesn't have a URL. The image on the left is from a patent filed in the U.S. in 2002 and the image on the right is a product for sale to men in Toronto.
The Japanese product for women comes in seven sizes from hips of 82 to 102cm. Priced at $40.
