I think Tina's & Mila's looks cool, and it is nice to see males wearing the extra costumes. But even then, I find some of the character's costumes not very interesting from outfit design & even which characters got the outfits, even Christie's & Helena's look way more interesting. (I also think Kokoro looks ok)
Outfit Designs I dislike: Kasumi, Ayane, Momiji, Marie Rose
Character choices I think doesn't fit: Hitomi & Lei Fang
The only character I think doesn't need to be part of the Cop DLC is Nyotengu considering she is not from the human world. Another thing is if the group behind the DLC costumes is considering every female needs to wear a costume from the same theme you should seriously not leave behind characters like Lisa & Rachel (which I've mention part of Sexualization: Too Much topic "Ignoring other characters is not a good decision"), and if they want each characters to have their own taste of fashion part of the choices they've made (including this DLC) is not the way to go. (at least make that character & theme mix together aka make them look unique) So overall, I think they could've done better.
