This outfit reminds me of the gear that the women of American Gladiators would wear. Very sexy though, the one piece with a hole cutout in the middle. It screams of "This outfit was designed so I could be mostly covered up, but still be able for you to see my bellybutton".
And a bikini for lower belly goodness.
