Business in the front, NOTHING in the back!!
SI Swimsuit model Haley Kalil -- wife of NFL offensive tackle Matt Kalil -- came up with a way to follow her mom's "no bikini" rule and still show some skin at the same time:
One-sided one piece suit!!! ... and if you've never heard of the term, it's exactly what you think it is.
"MOM IT’S TECHNICALLY A ONE PIECE ud83dude02ud83dude0eud83dude02," Haley said of the suit choice.
Of course, the model was kidding about the whole "no bikini rule" ... considering she's been spotted in the Sports Illustrated shoots for years.
