Kinda disappointing by the amount of conflicts on those items - greaves that can't even be worn with pants? That seems strange to me. Still, I'd be interested in seeing what all can be done with that Valkyrie set... might the greaves or cuirass work with other hip and underwear items, such as the Pareo or Hip Skirt, or Chainmail or Bustier? The picture linked to in the other page showed the Valkyrie set being worn over the Hunter's Suit, so if it's compatible with others that might make it more versatile.
All in all, the only pack that interests me right now is the Valkyrie set... never been much a fan of fetish costume DLC, save perhaps the Maid Pack a while back, which included a fair amount of pieces. Still, considering the potential packs we have coming up (more SCV Character Equipment, some SCIV equipment, more modern costumes, those colonial / wedding outfits, and what looks like another Tekken pack,) I don't mind a little bit of slack this time around. :)
