Maybe Kim Kardashian was in Vail for too long because it looks like she's mistaken her ski googles for sunglasses! Those things are huge!

Wearing the seriously sizable sunglasses, the mom of two and her sister Kylie Jenner stopped by the studio in Burbank, Calif., on Wednesday to film some scenes for their reality show Keeping Up With the Kardashians. For the studio stop, Kim donned a super sexy sheer to with a strappy bra underneath, along with a bodycon skirt and sexed-up patent leather boots. We're constantly amazed at the size of Kimbo's rear!

Looks like she's also finally switched up her 3/4-length post-baby uniform! Kanye West's lady love has been wearing some version of the same outfit for the past few months -- so we are glad to see that she's going back to her more fierce style.

Kylie opted to wear a black top and draw-string pants. She paired the look with a midnight blue duster coat and cut out heels. Ky is looking more and more like Kim by the day -- it's crazy!

Meanwhile, the visit to the studio comes two days after Kimbo admitted in an online fan Q&A that the craziest place she's ever had sex was a, "public movie theatre." Yikes!
