Mrs Kanye Steals The Show At Khloé’s 30th Birthday In Plunging Corset Dress, Kourtney Wears Jumpsuit [Pictures]

It may have been Khloé Kardashian‘s 30th birthday celebration, as expected, all eyes were on Kim Kardashian. The reality star, 33, wore a royal blue Ulyana Sergeenko corset dress with a thigh-high slit and her favorite Tom Ford gold chain heels.

The plunging neckline showed off Kanye West’s wife’s ample assets.

Her now-pregnant older sister Kourtney went for another bold look in a black and white printed jumpsuit. Her barely-there baby bump was covered up in the loose look.

The famous family enjoyed a yacht party off the New York harbor in honor of Khloé’s milestone birthday.
