Stephanie unveils the sprawling floral design anyway, which winds its way down the side of her torso and ends at the hip. Naturally, Nat wants a closer look and pulls on the waistband of her sister's pants to get one. Only, when she does:

"My underwear. These are my underwear!" Nat cries.

And while Liv suggests that Stephanie "stole" the garment, the eldest Halcro insists they fell into her lap fair and square.

"They were handed down to me," she explains during a confessional interview, dubbing them "magic panties" per their unparalleled comfort levels. Plus, "they're discontinued," and Steph's been hanging onto them "for dear life" ever since.

"I wear my sister's hand me down underwear," she shrugs and takes a sip of vodka soda. "Deal with it."
