I think Mika is wearing the same dress she's wearing in the [YES] cover/booklet photos in the Sony Hi-MD WalkMan with [LEGEND] -This is the one where she's wearing a black dress first and then a white one, not the one with the black dress with the red chains. You can see the same stitching along the side of the dress in both pics.
I guess Mika either really likes that dress or she couldn't afford something new for the album photos
