Kim Kardashian -- Baby Shower Is In-Tents ... And Khloe Shows Up (PHOTOS)

Kim Kardashian went full girlie for her baby shower -- as in a Girl Scouts themed party -- a family event big enough to get Khloe Kardashian to leave Lamar Odom's side.

All of the the Kardashian/Jenner sisters showed up Saturday to a Beverly Hills home wearing matching pajamas for the party, which recaptured a piece of Kim's childhood ... the movie, "Troop Beverly Hills." They even had tents in the living room, and of course ... Thin Mints and Samoas.

Kim's baby shower was originally cancelled due to Lamar's health crisis, but with his condition stabilizing ... they decided to go ahead, since Khloe was now able to be there.

No word if Thin Mints were frozen before serving, but everyone knows they should be.

Right?
