Just compared the costumes (recolors excluded) for male characters in DOA5 vanilla and DOA6 vanilla.
DOA5:
11 guys, 40 costumes, 2-5 per character, every character starts off with 2 costumes, the rest has to be unlocked.
Additionally the First Time DLC Pack shortly after release added 4 male costumes for free, giving Akira and Gen Fu a third costume. So:
11 guys, 44 costumes, 3-5 per character...
DOA6:
11 guys, 21,5 costumes 1.5-2 per character, every character starts off with 1 costume, the rest has to be unocked.
(I counted Diego's second costume as 1,5, because it just misses the jacket.)
That's a really awful development. It is showing even less interest in and less care for the male characters.
