Apparently, some women have started wearing their bikini tops with the halter straps tied on top of their chest instead of behind their neck.
It's being called the "upside-down" bikini trend . . . and it looks like there's just a huge cleavage hole in the middle and nothing holding up your chest.
So you probably need to have large breasts that are either very firm or very expensive to pull it off.
But if you do, prepare to be the hit of your family's Fourth of July barbecue.
