Actually Selita's would be the cheapest. Selita's whole set, the Bra, the panty, the hair pin, and the garter all together totaled 4.5, so her's would probably be the cheapest. As for how the 1997 once could be three million, great quality of diamonds...and the big one in the middle as well. Marisa's bra, is very cheap...the bra's diamonds with as many as their are, aren't the best quality because of how many are their and how little it totals with that many diamonds and the middle diamond as well..that middle diamond itself is worth probably 2 million dollars, because in comparison that's at least what the others cost (the big diamonds in the other bras) so that leaves only 1 million to do the whole bra for her, over pretty large cups, so I'd say this bra may not be the cheapest, but it's defiantly not the same quality as the others
