Kim K in a plunging white dress

Mrs West celebrated her birthday at Tao nightclub at the Venetian Casino and Hotel this past weekend.

Her hubby, mom, Kris Jenner and sister Kloe Kardashian joined Kim in Vegas to party the night away.

Kim’s dress was definitely the talk of the night! 

The birthday girl showed up wearing an Alexandre Vauthier plunging white dress and showed off some serious side boob. 

We just can’t help wonder how she managed to keep her assets contained. 

Here are some pics the Keeping up with the Kardashians reality star shared on her Instagram page:
