Kim Kardashian wears same maxi dress worn by sister Kourtney when she was pregnant.

At least they share cloths.

As sisters they're used to swapping and borrowing each other's clothing.

But Kim Kardashian and her sister Kourtney have somewhat different body types, so an identical outfit doesn't always have the same effect.

Kim, 32, was snapped on Wednesday struggling to contain her ample curves in a low-cut maxi dress, while Kourtney, 33, looked decidedly more elegant in the exact same frock while pregnant with her second child Penelope in 2012.

Kourtney wore the cream Grecian-style dress in June while filming scenes for the family's reality show Keeping Up With The Kardashians in San Diego

The reality star, who was eight months' pregnant at the time, looked slender and sophisticated in the frock, which fit her perfectly.

Fast forward nine months, and Kim emerged wearing the same dress when she made a stop for frozen yoghurt in Los Angeles.
