The catgirl outfits make me smile every time. They're so stupid but they're dumb in an amusing way as opposed to most of the ''sexy'' (urgh) costumes which just make my palm smack my face with excessive force. Wish they'd gone for the slightly nicer fur-trimmed versions though.
The others look good enough. It's nice that they're bringing in some of the Dimensions costumes rather than simply porting DOA4 ones, which is what I would have assumed this early DLC would have been.
Only one I take issue with is Ryu's, because it's so obvious that from now on all we'll see online is that, constantly. It's like in RPGs if there's an option to have an oversized sword and black armour, that's what everyone picks. Ninja that looks like some crazed fire demon? Yup, gonna be seeing that an awful lot from now on and it's going to get real boring real fast.
