, Kanye was recorded walking hand-in-hand with
Bianca, 29.
The fashion designer donned a winter-appropriate, long-sleeved black top with gray pants for the Sin City outing.
Bianca appeared to be dressed for the beach as she showed off her ample chest while sporting a barely-there black bikini.
The model paired the micro bikini top with a coverup and went completely barefoot as she and her husband trekked around the casino.
Video screengrabs were posted to a Reddit board titled, "Bianca and Ye in Vegas… girl lost her mind and her shoes."
In the comment thread, one person wrote, "Gross. Imagine walking barefoot on [the] carpet in a casino."
"I don't care how rich you are but you should never walk around Vegas barefoot! I'm just imagining her stepping on tiny pieces of glass," said a second.
A third commented, "It's so gross," before adding, "They look ratchet."
They also speculated that the casino "made Bianca wear the shorts against Kanye's worst wishes."
Another user questioned, "Is this top supposed to be sexy? I feel like this looks goofy."
Someone else agreed, writing: "Right?! She’s got an amazing body, beautiful face, but somehow manages to look goofy to put it kindly."
"Kanye loves to humiliate his muses," suggested another commenter.
