Help! Can Someone Explain To Me The Science Behind This Instagram Model's American Flag Bikini Top Please???

Please excuse what is undoubtedly the creepiest title in the history of the internet. It was Smitty's idea to use that as a title, not mine. Such a goddamn blockhead.  

I have been staring at this picture for the better part of 20 mins trying to figure out just how in the freaking heck this American flag can POSSIBLY provide ample support for our girl Terann here. That cloth is thin as can be! She must be SO WORRIED that she'll accidentally have a slip when she's least expecting it! 

My mind is racing. Maybe there's some sort of adhesive product? A suction cup perhaps? Maybe it's something really cool that I don't even know about? 

Whatever, none of us give a shit, just give us more Terann.  Much much more, thank you. 

Thank you!
