Kate Upton is not one to shy away from skimpy and revealing clothing, but she's now proved that even full coverage can be sexy.

Yesterday, the 22-year-old Sports Illustrated swimsuit model posted a photo of herself to her Instagram in a yellow pair of granny panties and a tiny black tank top, and she looks incredible!

"In honor of #grannypanties being HOT again!," the caption read. "I'm back in trend betches! @justinverlander I told you!! #imsoexcited #ijustcanthideit"

Apparently, her MLB star boyfriend just didn't believe that granny panties could look this good.

It was recently revealed that full-coverage underwear were making a huge comeback, and who better to prove that the trend works than Upton?

We're so used to seeing Upton looking amazing in skimpy bathing suits and following the "less is more approach," so this particular trend is definitely something new for the model, but she sure knows how to rock it!
