I really don't see the problem here. How is this different from any other cheap-o Halloween costumes out there? This is exactly what I would expect from these types of costumes. No different from the Batman, Spider-Man, Iron Man, Hulk (need I go on) costumes you find at Zellers or Wal-Mart at Halloween.
Everyone knows that if you want SA costumes you gotta make them yourselves. By the way I love the movie costumes and I'm a fan from back in the 80's when the book first came out. They captured the essence of the suits perfectly.
