I simply think that the PV was a resume from some of her old PVs, like :
Together when.. : the hat, and the longcoat, I think
Dearest : the part where she got chased
alterna : simply when she sings in the close up part, with feathers on her hair
GAME/JEWEL : her red oversized gown is similar to the ones on those PVs
About You : the part when she sings while "playing" with her gown.
and as a bonus and commemoration when she got chosen as the Wacoal spokeperson : the part when she sings in lingerie
