Kim Kardashian looked ravishing as she arrived at her star-studded 43rd birthday bash in Beverly Hills on Friday night.

The SKIMS mogul — who officially rings in her birthday on Saturday — strolled up to the entrance of the swanky restaurant Funke in a sexy red dress.

The busty starlet’s dress showed off her famous curves through the countless cutouts that ran down the sides.

They were tied together with laces similarly to the dress’ bikini-inspired bodice.

The mother-of-four was joined at the soiree by her sisters Khloe Kardashian, Kendall Jenner, Kylie Jenner and their mom Kris Jenner.

It was also attended by the family’s close friend and Kendall’s BFF Hailey Bieber and Kim’s close pal Lauren Sanchez, who is the fiancée of billionaire Jeff Bezos.
