North West and Penelope Disick Play Dress Up With a "Real" Mermaid

North West and Penelope Disick got a head start on Halloween with adorable matching mermaid costumes. Kourtney Kardashian took to Instagram on Wednesday to share a precious photo of the cousins listening carefully to a "real" mermaid while hanging by the pool this week. The day before, Kim Kardashian shared her own snapshot of North and Penelope rocking their underwater outfits, with the caption, "Little mermaids." The Keeping Up With the Kardashians star also teased her Instagram followers with a picture of a mermaid swimming in the pool, writing, "Mermaids are real."

Just yesterday, Khloé Kardashian posted a goofy photo of North wearing crooked glasses on Instagram, captioning the shot simply, "Mood." It looks like we'll be seeing more fun moments from the family, who arrived in St. Barts on Monday. In the meantime, check out how the Kardashian-Jenner clan is living it up during their Summer vacation.
