they're the promo outfits for the whole tour, i think that particular photo was used for the poster and one of the clear files. i don't actually like the outfits too much, but in certain photos they looked good.
that's true, they did better than usual for Chou HAPPY SONG with the outfits, but they do so with Buono! as well. i'm considering the fact that this is a Berryz PV, and the only ones times they do tasteful/modern outfits are when they are using casual clothes (Dakishimete, Maji Bomber, Rival, Heroine). judging by the description i'm guessing we're getting costumes, so they are unlikely to go the route of the calendar. granted, it's possible for them to still pull off cute-ish costume dresses/outfits (i have hope!), but i long for the day when we WILL get something like the calendar photo. we got close with the cover of 7 Berryz Times, i just wish those outfits or similar had made it into a PV like Aa, Yo ga Akeru.
edit: here's the link for Berryz Station goods..
