If you picked up Dead or Alive: Dimensions late and missed out on the free downloadable costumes, Tecmo Koei will be re-distributing them from August 15th until September 19th.
There are 34 costumes in all, and you’ll be able to grab one everyday by connecting your 3DS to a Wi-Fi connection. You can view some of the downloadable costumes in this post. Don’t hope for anything too skimpy, though…the chosen costumes are all in fairly good taste.
Update: Reader, banballow, points out that Team Ninja’s Facebook page mentions a second re-distribution period from September 19th – October 22nd.
