RMBI/AKM-GSIVa-va-voom!
We know the nude bra was under there, but Kim Kardashian was otherwise playing a game of how-low-can-you-go during her day out in San Diego, Calif., today.
The E! star was in town to visit her maternal grandmother, Mary Jo, along with her daughter, North; mom Kris Jenner; and sister Kourtney Kardashian, who had brought son Mason and daughter Penelope along as well.
For the outing, which included a trip to the famed San Diego Zoo, Kim wore a distressed denim skirt and a matching chambray shirt, left sexily unbuttoned nearly down to her navel.
Hey, why abandon signature style when you're on the road?!
Kris certainly seemed to have a time today, sharing a photo of her holding grandbaby North while they were checking out the giraffes. Judging by her expression, the 1-year-old might have been a bit afraid that the giraffe was going to eat her hand, but everyone left with appendages intact.
"Thank You @SanDiegoZoo for the most amazing day!!!! #memories #churros #myoneyearoldbirthdaywashere! #cantwaittocomeback! #family," Kris captioned the funny pic.
North's cousin Mason seemed far more interested in meeting the giraffes than she was, the tot not looking at all concerned when mom Kourtney reached up to feed one.
Kourtney, who's pregnant with her and Scott Disick's third child together, was showing off her baby bump in a fitted striped sweater.
"Another fun day at the @sandiegozoo!!!" she captioned the pic of her holding Mason by the giraffes.
Don't miss more family fun on a new episode of Keeping Up With the Kardashians this Sunday at 9 p.m.
