Uh oh, looks like Sienna Miller made the mistake of flashing bystanders because her bikini didn’t fit very well. I wear bikinis. I get it. Stuff like this happens. But it usually only happens when the bikini has been worn way too many times and has lost all sense of elasticity and resilience. Or maybe the suit was just too big to begin with. Either way, it resulted in a serious blooper. Let this be a warning to all of us the importance of wearing a bikini that fits properly. Nice arms though.
