Kourtney Wears Khloe's Kim's Clothes For Maternity Wear!

Remember when Kim Kardashian said back in September that her sister Kourtney will borrow Khloe‘s clothes for maternity wear?
Guess she was just covering her big booty! Or should we say she’s covering Kourtney’s?
About 2 weeks ago Kourtney stepped out wearing this cute dress while attending Kim’s birthday party in Las Vegas. But Kim wore it first all the way back in May!
We guess the proportions are the same. Kim’s baby bump is just on the other side and lower!
