Thought I would share this since the costumes are a one day thing.  Just got this SpotPass message and I thought I would share the schedule for the costumes.  Please note that this is for the NA version of the game.  I'm not sure about other territories.
 
5/24 (Tue.) - Kasumi
5/25 (Wed.) - Ayane
5/26 (Thu.) - Kokoro
5/27 (Fri.) - Lei Fang
5/28 (Sat.) - Tina
5/29 (Sun.) - La Mariposa
5/30 (Mon. - Hitomi

neat. thank you for the share! i didn't get a spotpass message.. ah, whatever. i got my Kasumi costume today~ 

La Mariposa? Pfft, Christie should've been in the first week. :P

Just go the Ayane costume.  It's 1:13 PM CST here.
 
Just to give you guys a heads up, while your notification light wont blink, there will be a blue dot next to the DOA:D icon in the Home menu.  That shows the game has new SpotPass content.

I've gotten both the Kasumi and Ayane costume so far.  The Ayane costume actually downloaded while I was playing the game.

No guys???

Ive been getting them everyday in the UK (only Hitomi left tommorow) they go up at about 2/3PM here I dunno if that's the same in the US.

Out here in the Pacific U.S., I've generally been playing the game in the evening.  My first costume download (Kasumi) happened sometime Tuesday night/Wednesday morning, but Ayane and Kokoro's costumes were both downloaded at some point during the day or evening the following days.

No guys???

@Hailinel: I like Jann Lee's stuff lol

@Hailinel: 

The second round of costumes havent been half as interesting as the first, with only one left  here.  I tend to find more of the unlockable ones in the game to be far more interesting. That teletubby-thing is terrifying!
