Actually, if you go and peek at the female characters in MK, less them half of them are "popping out" out their clothing.
MK1: 0 - 1 in boobage (in fact, it was a horrid green leotard!)
MK2: 0 - 3 in boobage (they wore a one piece that had a turtleneck)
UMK3: 1 - 6 in boobage (the only thing other than a scant amount of cleavage was done in clay...)
MK4/Gold: 0 - 4 in boobage (they got a lot bigger! but still more covered than showing)
MKDA: 2 - 5 (Nitara and Li Mei, the others were mostly cloth covered about the naughty bits)
MKD: 3 - 7 (Jade, as sexy as she is, was completely covered except for her arms, stomach and legs. Mileena, well, that was a good view there

. Sindel definately wasn't setting a good example for the impressionable princess... Li Mei was falling out yet again. Ashrah looked like a school marm as prim and proper as she was dressed. Tanys had a bodice that only showed a smidge of cleavage and Kira had a bodice that wasn't all that revealing, at least not of the flesh)
So there you have it, MK is not a game that seems to be geared to showing off all of the naughty bits us naughty boys want to see. That title I think is held much more firmly by DOA.
