It's best described as a "scary sweat-jumpsuit" or a OnePiece (www.onepiece.com) and it's invented by three Norwegian men. This particular store is located at a prime location in Gothenburg (Arkaden, for those who know) and this is their only product.
How did they came up with this design? I guess it could be somewhat practical for men when using the men's room (see the crotch-zipper), but for us ladies it would be a hassle. And another question, have you ever felt the need to zipper your entire face? My husband might want to zipper my face at times, but I would like to see him try!
For those of us who haven't understood the obvious, this is apparently design and innovation. It's edgy and provocative! It's a statement piece. And it is all yours for 1350 sek ($200)!
