What character are you talking about? If you're talking about Ayane & Kasumi, they have tons of great costumes (along with the obvious fetish nonsense). Team Ninja did a pretty bang up job with the character visuals in DOA5LR.

don't forget the price will increase too

To be fair, the costumes in DOA5 weren't too expensive. If we're getting less in 6 then it makes sense for them to increase the price. As long as they're good though, then that is all that matters.

No one particular character, its just that I'll go through the wardrobe of some characters who were blessed with dam near 70 outfits, and there will maybe 1, 2, maybe even a whopping 3 costumes that stand out to me. With that much variety your bound to find something that you'll like, but is still prefer a quality over quantity approach in the next game
