Pregnant Kim Kardashian squeezes into another skintight dress as she and Khloe put on a busty display for family getaway

Perhaps the only thing racier than Kim Kardashian's day-to-day attire is her pregnancy fashion.

And on Tuesday the 34-year-old kept up with appearances as she took a trip down to San Diego, California, for a family getaway.

The reality star, who is pregnant with her second child, was joined by sister Khloe as the two both wore plunging tops.

Kim opted for a very low-cut - and of course skintight - dress as donned strappy heels for the fun day out near the Mexico border.

Keeping her hair slicked back, the selfie queen sported a choker and dramatic eye make-up as she covered up in a long coat. 

The ladies headed into George's at The Cove to have dinner with their grandmother Mary Jo for a belated birthday get-together. 

Earlier in the day Khloe was seen carrying her three-year-old niece Penelope out of her SUV.

Khloe was very hands on throughout the day as she was also seen behind the wheel for the family trip, with Kim, 34, sitting shotgun.

Always on point with her style, the reality star sported shiny reflective aviator sunglasses and big gold hoop earrings.

Completing her getup were blue jeans as she wore her light coloured tresses in flowing waves over her shoulders.

Kim, meanwhile, sported a choker and what appeared to be a long dark coat as she let her younger sister do the piloting for the day.

Little Penelope was dressed in a matching floral top and bottoms as her hair colour matched her auntie Khloe's.

The family were busy filming their reality show as small cameras could be seen attached to the inside of the car, documenting their every move.
